Here's what I know, and this is coming from someone who didn't really trust Trump when he was inaugurated.
He didn't start any wars.
Unemployment at record lows (before COVID).
Stock market at record highs.
Lower taxes, I kept more of my paycheck.
Renegotiated trade deals with China and Canada & Mexico to benefit US.
You can point out mistakes about response to COVID but you can't convince me Biden, Hillary, or Obama would have done any better.
He did all this while being harassed EVERY DAMN DAY of his presidency by false charges of collusion and a bogus impeachment. Please tell me, what exactly did he do that was so damn bad other than being mean on Twitter? Democrat or Republican, any president that can point to each of those accomplishments would have my vote for re-election.
