If you really want to know how Trump got elected

You could talk to your good friends and Neighbors who voted for him. This will likely be much more effective compared to visiting liberal websites or even arguing with anonymous conservatives on the internet. Talk to people that you normally like in any other situation who happened to vote for Trump. If when you're finished you sincerely believe they're racist bigots then I would suggest you stop being friends with them. Otherwise you might consider not being such a big a******* about the election
