People withheld their votes from Harris because of her complicity in genocide, and her pledge to continue to enable genocide. It is the number one reason people who voted for Biden gave for withholding their votes from Harris. Genocide is a red line.

Withholding votes from Harris does not mean these voters then voted for Trump. Many boycotted the election. A smaller number voted 3rd party.

Harris probably would have won if she had renounced the pro-genocide policies of Biden and pledged to cease arms transfers to Israel. She only had to win a few swing states, and swing states like Michigan with a sizable population of Palestinian diaspora were undeniably lost due to her doubling down on genocide. Heavily Jewish Zionist "blue" states like New York weren't going to swing Republican, and heavily Christian Zionist "red" states were never going go to the Dems anyway.
