As the United States braces for pivotal midterm elections this November, there’s a new and unexpected issue on voters’ minds in many states: President Donald Trump’s escalating trade war with Canada.
“Canada is our friend, our closest ally and our biggest trading partner,” Maine Republican Sen. Susan Collins told Politico in an interview published last week.
“This is not China that we are talking about. This is not an adversarial country. And … our economies are so linked, if you try to hurt one you end up hurting Maine.”
Collins has long been a political force in her border state but Trump’s unpopular policies — including his tariff campaign against Canada — have put her seat in jeopardy.
Canada is Maine’s largest trading partner and many of the state’s critical industries, like seafood and lumber, are integrated with Canadian sectors. Collins has acknowledged that the tariffs on Canada are “terrible for Maine” and are making the job of re-election a lot harder.
While Collins’ seat in Maine could be the most vulnerable, it’s not the only one being rattled by Trump’s attacks on Canada as Republicans look to hold power in Congress.
Matthew Lebo, a political-science professor at Western University in London, Ont., said long-term historical trends show that, in general, midterm elections are usually bad for the party of the president in power.
He said while many political observers have been predicting for some time the House will flip to the Democrats, the Senate could also be in play now.
“Some of the key states that have become battleground states are ones with really close trading relationships with Canada,” Lebo said, pointing to Alaska, Iowa, Maine, Michigan and Ohio.
“You’ve got Republican candidates who have to be confronted with trade policies against Canada that are making it harder to export stuff to Canada and are making some things really expensive for people in those states to import.”
The relationship between Canada and the United States was upended by Trump’s return to the White House. Suddenly, Canada found itself the target of tariffs and threats of annexation from a president who sees it less as a close ally and more as an adversary.
While Canadians have been laser-focused on the upheaval, many Americans have been oblivious to the downturn in the relationship. That changed last month when tensions escalated after trade talks between the two countries broke down.

Trump subsequently imposed 50 per cent tariffs on an array of Canadian goods, from hockey sticks and cement to honey. Trump also ramped up his anti-Canada rhetoric and signed an executive order to rename Lake Ontario as “Lake America.”
Canada is set to implement its retaliatory duties on Tuesday. Many are aimed at key industries in states where there are competitive midterm races.
Both countries have accused each other of adding last-minute changes to negotiations. Trump’s team has spread out on American news stations in an attempt to place the blame at Ottawa’s feet and to accuse Prime Minister Mark Carney of tanking a deal for domestic political reasons.
Carney, pushing back on those claims, said last week that he doesn’t think “appointed, unelected cabinet members in the United States are experts on Canadian politics.”
It’s not clear whether the Trump administration’s claims about the trade war are breaking through. Both the tariffs and the order to rename Lake Ontario are proving to be very unpopular with Americans.
An Ipsos/Reuters poll published last week suggested two-in-three Americans disapproved of the lake’s name change. It also found only 20 per cent of Americans supported higher tariffs on Canada.
A source with who was not authorized to speak publicly said Republicans from border states approached United States Trade Representative Jamieson Greer during an event at the White House on Sept. 2. They told Trump’s trade czar to find an off-ramp from the trade war because it was becoming politically toxic, the source said.
Democrats have been quick to jump on the weaknesses the trade war with Canada has exposed. Michigan Democrat Senate candidate Abdul El-Sayed said last week “this vanity war is not a war with Canada.”
“It’s a war on Michigan because we have to pay the price,” he said. “And we pay it every single day for goods that should not cost as much as they do.”
Lebo said some Republican candidates are already trying to distance themselves from Trump and his tariffs on Canada.
While New York’s Democrat Gov. Kathy Hochul has been vocal in her criticism of the trade war with Canada, her Trump-backed opponent Bruce Blakeman has been harder to pin down.
“I’m not going to talk about federal issues,” Blakeman said when asked by Spectrum News about the trade tensions in late August.
Other Republicans are doubling down. Anthony Constantino, a Republican running for a House seat in New York State, said renaming Lake Ontario was an act of “marketing genius” and claimed “Trump showed strength in negotiations with Canada by playing a card he had available to play.”
Christopher Sands, director of Johns Hopkins University’s Center for Canadian Studies, said the bigger picture is that the United States economy is in a state of flux, which is causing a lot of uncertainty ahead of the November election.
The war with Iran, rising gas prices and tariffs have affected domestic investment and employment at a time when the top issue on the ballot box is affordability.
Sands said while neither party can expect a “cake walk” in November, Trump has handed Democrats an opening with his attack on Canada.
Democrats have long been looking for something to unite centrist party members with more left-wing factions like the Democratic Socialists of America. Sands said the trade war with Canada could do just that.
“They feel that they can make the case that this is a senseless trade war,” he said.
“I think most Americans don’t even understand why it’s happening.”
“Beautiful women are waiting to say hello—join us today! 💋” ………………..> fillboards.com/girls33
Will the Democratic be able to cheat enough to win?
Is the only question surrounding the midterms.
@John 106pm. If the democrats are crooked, why has the USA plunged on world democracy and freedom indices since Trump came to power? Trump is the antithesis to democracy.
They keep saying that Democrats will win because Trump and TDs, but the Democrats are broke and have been taken over by communists calling themselves socialists.
Nobody ever said
“Gas prices are so high, I think I will vote for the communists who want to dissolve the electoral college and pack scotus”.
Wait until the mid term elections in the US…Trump is cooked…after the Republicans lose control of Congress and possibly the Senate, we’ll see articles of Impeachment brought against Trump by early 2027 and many of his executive orders will be reversed…
Brian calling Trump a rapist. Guess this blind sheep did not check 8n on Carney or Trudeau. Carney ex brother in-law was former prince of England. Carneys friendship with Epstien was not j7st plane hopping it was time spent on the island.
Funniest part is that the pants down elbozos up the rear think Canadian media is actually telling them the truth. Con man Carney and his information control and communist style of media control pushing those who can’t think for themselves to support slavery.
BTW biggest and longest slave owners in history are from middle east. Not western society you blind sheep.
I thought it was Elbows. Why is Maine seafood allowed to come up tariff free. Where is my Boutbon Lard Ford?
And just by coincidence Canada removed counter-tariffs on seafood from Maine….
Czarney likes his sea bass I guess…
US added 142000 jobs, Canada lost 42000….
Sounds like winning to me….
Interviewing Democrats who hate Trump? You call this journalism?
Next time make that bullet stick to Trumps head the world will be a better place without him
Most Americans don’t care anything of Canada. Not a big issue for them and Carney has no character or charisma like Trump
@david best: thanks for revealing your name, we at least now know who the real village idiot is!!
@rick Wilson: there are similarities but there are also differences, depending on where in the UK people live.
Trump and his MAGAt Repukelicans are a total waste of space & oxygen!! November can’t come soon enough!
Carney and the Liberals are the enemy within. Trump works for the betterment of the USA. Cant say the same with Carney and Canada
Anonymous is a village idiot…with too much time in his parents bsmt.
@Anonymous. UK folks are very similar to Canadians. Lol
Orange man and his brainwashed Repugnantlicans spewing more garbage towards Canada than ever…..yep, worried they are about the upcoming midterms. Awesome!!
I was born in the UK and travelled frequently for work. I find Canadians to be some of the most courteous, kind and selfless people on the planet!
I was born in Africa and travel frequently abroad with work. Generally, I find Canadians to some of the most entitled, selfish, and self absorbed people around.
@Craig Dearborn 555 pm. Most of us in Canada aren’t under the delusion that things will change in 2 years. If it’s a democrat, entrenched trade interests will make it difficult to reverse policy. We aren’t waiting, we’ve moved on.
I hope Trump does a full blown boycott on Canada. Also, GOP will win in 2028 and Elbows Up Canadians will have to wait another 4 years as they won’t fix what is bad on their side of the border. Hoping for a sympathetic Democrat.
Only twice since the American Civil War has a sitting president gained seats in the midterms !!! Safe bet global that Trump won’t despite your whimsical storyline.
Murican MAGAt delusions so obvious on this thread…..must be tough paying inflated prices on everything while their orange heroes piss away their money on their idiotic tarrifs and a meaningless war!
Canadian false self importance is so obvious on these threads. Must be tough to be so reliant on the USA and irrelevant to the rest of the world.
Hey tex. As I can clearly see, you are American and don’t don’t anything about the Canadian economy. Look in your own backyard with all the trash that’s there before you point at your neighbors whose backyard is much cleaner
@Guevera. USA doesn’t need to “prove” anything to Canada. This is about business and mutual interests. USA needs to do right for itself and owes nothing to Canada.
It’s time to drastically pullback trade with the US. The current administration are bullies . We need to take our resources elsewhere.
No matter how high gas and everything else go up in the US it’s always going to be higher here.
Americans need to prove that their friendship with Canada is genuine.
@Anonymous. Correct it is 2026, and Canadas economy is still poorly performing. Over 40,000lost jobs in August.
@Brian. Those that voted for Trudeau 3 times and now Carney must have less brain cells then the “Trumpers” that you mock. People in AZ love Trump as he cleaned up the south border. Canadian tariffs is not a concern for them, nor should it be.
I am a proud CDN who has also loved the USA my whole life, been to 29 states over 60 yrs. Met so many great Americans I still keep in touch with and they come visit me. They all hate Trump and in their words, TRUMPERS are the dumbest people on the planet who drink the White House Rapists coolaid.Those are the words of Patriotic Americans.
Under Trump’s US, the world see the US in the same category as Russia and China.
@Elizabeth Perkins. There is something called comparative advantage which Trump is ignorant of. No country can produce everything, to do so would be economic madness.
@ Rick Chapman – It’s 2026 now.
A lot of comments say Trump is doing right by the USA: each US citizen owns $117K!!! And that number is going up.
I like Trump tariffs. Texas economy doing amazing. Canadas problems are not the USAs.
Keep voting for the orange circus USA and you will continue paying more for groceries, gas and everything else l caused by the idiot tarrifs and meaningless war.
Canada economy was doing poorly before Trumps tariffs. We can thank Trudeau and Carney for that. Canada has the worst performing economy from 2022-2025. Canada lost over 40,000 jobs in August while USA gained over 160,000.
Trump is a fn lunatic good luck usa
Guess Not

Onward and upward Canada, keep it up.
@LPC/CCP Coalition
“This is not China that we are talking about.
Well,Actually…”
You very smart Roundeye Canadian Conservative !
Soon you will be our slaves thanks to Riberal Party Canada
“This is not China that we are talking about.”
Well,Actually….
If Canadian dollar is too low for you Americans and you are all powerful world power please make US dollar equal to Canadian
Problem solved
@Ben. Correct they are talking about Maine and on politician who will be losing. Lots of American agree with Trump and the tariffs. Trump is doing right for the USA, not Canada. That is his job. I understand that is not popular up in Canada.
@Naomi Wilson at 1148. As per you the article, you would have noted the trade war has become an issue in many states. Those are mainly border states. So your statement “Actually it isn’t” appears to be incorrect.
Actually not their not because what American’s realize when Trump tariffs Canada that means American will buy American therefore tariffs mean nothing to them.
The same can’t be said for Canadians and Canada as they make their whole identity about Trump.
Actually it isn’t. For instance in Texas nobody cares at all or likes the tariffs.
Great! Hopefully the midterm results sends Trump a message. Meanwhile, Canada must bravely carry on in this trade war with the US.
