If the entire GOP-E apparatus was behind a candidate, yes, I can see all sorts of people having problems voting for that creature.
The “Never Trumpers” already did that to Trump, twice.
Well, if a general election were DeSantis vs. Biden, I would certain choose DeSantis. Other Freepers can make their choice, based on whatever criteria they decide are important.
If Karl Rove liking him is more important to some people, than having four more years of Biden, I disagree with that sentiment.
