Should the unlikely happen and somebody needs to replace Trump before the election, the pick should be somebody MAGA, not Meathead or one of the seven dwarfs.
Sure, and if Trump has amassed enough delegates and goes before the convention, then those delegates will decide. But, like it or not, there will be a huge bias towards someone who has bothered to go out and campaign.
Just out of curiosity: who would you pick to replace Trump if for whatever reason he wasn't able to be the nominee?
An insight I have is that MAGA doesn't have a lot of depth. Originally DeSantis was considered MAGA, but in challenging Trump he seems to have aliented the MAGA true-believers and become a disliked person, not as much as Pence, but close.
So, you've dismissed all of the remaining candidates (which to some extent I agree with) so then who would a convention dominated by Trump MAGA electors prefer?
It's not an easy question to answer, is it? And that's a weakness for MAGA in my estimation.
