DeSantis v. Newsome is more favorable for Republicans than Trump v. Newsome. DeSantis v. Biden it a TKO in second round. No Republican is going to peal off many Democrat voters and vice versa. It’s the independents who are in play. They find Trump off-putting and Biden repulsive, but no firm split. DeSantis and Newsome would be competing for the independents. Newsome might beat Trump, but it’s less likely that he would beat DeSantis.
