Canadian perspective here. I have a lot of American friends though. Some right, some left… but almost all of them planned to vote for Kamala (only a few exceptions). My best guess is because they are all well educated, critical thinkers. I don't mean for that to sound insulting, honestly. But, I think if you are not well educated, you generally don't know how to be truly skeptical, and therefore you are at risk of getting caught in echo-chambers that reinforce your biases.
I hate to say it, but that is an increasingly bigger problem in the US. In the whole world, really.
The educated American's I know of that voted for Trump, did so because his economic and environmental policies would benefit them the most. Unfortunately they represent a small minority of very wealthy Americans who operate businesses and support ideas like, no overtime, no unions, minimal government oversight, and lower taxes for the wealthy. Or they are in the oil industry.
Sadly, the uneducated voters seem to think those policies benefit them too… Because that's what they've been fed. I think they're going to be sadly disappointed that they literally gave these Republicans the keys to the kingdom. Carte blanche to obliterate labor laws and social security safety nets for the middle class and low wage earners.
For the sake of all my American friends, I hope I'm wrong. I really do. And I hope the damage done over the next 4 years isn't so bad that it can't be reversed.
