Not the person you responded to, but some polling indicated that something like 30% of people who didn’t vote for Harris, but did vote for Biden, chose not to vote due to the genocide in Gaza. That poll indicates that maybe some of those 30% may still not have voted for other reasons, but it was the main issue polled.

I have my own guesses, some of them align with this. Though could anyone expound further?
