I disagree that "their humiliating defeat on November 5 was due largely to their undeniable role in the Israeli war and genocide in Gaza." I definitely think it played a role and Dems would have won more voters with concrete promises to halt Israel's genocide and enforce US laws like the Leahy Law. People are justifiably upset with Israel crossing lines without Biden enforcing consequences, and the huge amounts of money going to fund genocide as opposed to being used domestically.

Was it really THE major issue affecting votes though? IMO the more significant issues were things like a feeling of "more of the same" when people are struggling and focusing on trying to win "moderate" Republicans instead of motivating a base they thought was guaranteed. Still, it's an article with valid points.
