Good fucking luck with that hurdle.
They need a two-thirds vote in both the House of Representatives and the Senate; or a conventio called by Congress at the request of two-thirds of the state legislatures. Then it has to be ratified by the legislatures of three-quarters of the states.
Even if they managed a super majority on both sides of Congress for Trumplefuck, there’s no way they’re getting 38 States to agree to that.
Don’t act like Canada hasn’t been seeing it’s own share of right wing extremists making their way into government.
