Why are you so concerned with "protest voters"? If every third party vote went to Democrats, Harris still would have lost.
It's way easier to blame a small amorphous group of people, but why don't you focus on winning? Harris got 6 million fewer votes than Biden. Do you think all those people stayed home because of Palestine?
Take this energy and put it towards something useful. Ignoring all the facts so you can punch left is pathetic.
