But are there Never Trumpers in a few House delegations who would vote with the Dems in their delegation and give Harris the win
Not enough. He may lose one or two. In the end, he'd win.
Trump has total control over today's GOP.
My point is that if this happens, there will be an absolute shitstorm from the "defend democracy" side.
And it'll be glorious!
If there are only 1-2 defectors in each state, it will not be an issue so long as there are enough Republican Representatives from the respective state to override them. As I understand it, Trump needs the majority of 50 states, not of 538 Representatives.
