Honestly, if you're a republican, Trump is the only pic. I'm no fan of Republicans, but this is clearly the Republican party punching the Republican populace in the face.
You haven't been paying much attention to the Republican party as of late, have you? "Circle the wagons and toe the line" has been their schtick for a while now.
Best polling to beat Biden. If you want to win or to get conservative laws passed, that is the way. Last time Trump was president, he put in a bunch of conservative judges, he has a track record.
