It's just like I said. Though he occasionally tweets things I'd prefer he not, I've been so impressed by the way Donald Trump has governed that I was compelled to vote for him this time around. Of the close family members who I know what their votes were, I know only 1 voted Trump last time and this time 11 (including me) are voting Trump this time. I don't even know someone by acquaintance that is claiming to flip the other way. I talked to one Biden supporter and after they couldn't tell me why they supported Biden and my telling them some pretty good reasons not to vote for him, they decided to abstain from voting at all.
If you, or someone you know, switched parties from 2016 to 2020, let's hear about it!
edit- Just wanted to add that I live in one of the bluest states in the country where it's assumed that 90% of people vote democrat, which just makes the fact that I know more people voting Trump than Biden more impressive.
I didn't vote in 2016 because I was trying to stay away from politics and I live in California anyway. I was happy Trump won though and after he won I did research and became a huge fan. My girlfriend voted Hillary last time because she was gullible and didn't know better, but I redpilled her and she voted for Trump this year. My siblings and other family members didn't vote but are now voting for Trump, some with the help of my redpilling of course. I've never heard of a real person who was a Trump supporter and isn't now. I think the polls are missing the big picture.
