Trump separated himself from the pack in 2016 by campaigning on building the wall, deporting illegals, draining the swamp, and locking up Hillary.
If he tries running on the same or similar issues this time around, the stench of bullshit will be too much to ignore except for his most devoted followers.
IMO, he'll probably run on "I'm not Biden," and I'm sure with how bad Biden is, he'll win just off of that.
The sad part is, this will be another wasted election to try and get an actual change candidate who won't sell out as much. Too bad Rand Paul has a terrible sense of what grassroots Republican voters want. Last time around, he was pandering to try in bring in more black voters. Fucking eh, what a mess.
If I had to guess...
"Look at how good we've had it in 16-20, then the election was stolen and everything went to shit. How about we do 16-20 again?"
