Maybe if democrats credibly supported something other than genocide, more people would have voted against him.
Or, maybe if she had been unequivocally anti-genocide or even anti-funding Israel without checks or guarantees from Israel first, she would have lost even worse. Sad to think about, but close to 1/3 of the US is irredeemable deplorables who have been shamelessly propagandized for over 40 years by hate media. Your own argument seems to distill down to everyone is a genocider. Can you really say that she wouldn't have lost more votes than she gained, and that the purity testers wouldn't have just moved on to a different issue they had with her and still sat out on election day?
