So many people didn't vote for the Democrats in 2024 because they didn't support Palestine and they lost as a result. If the Democrats become identical to the Republicans then why would any non-Republican even bother voting?
Paying lip service but not addressing that friction was a significant part of what killed the Harris campaign, IMO.
She had a bad hand needing to start out 6 months into an election cycle, and she played it poorly to boot. That's why this "we need to appeal to moderates/right wing" narrative is so frustrating. That's exactly what Harris did by trying to downplay Palestine/defend Israel and refusing to talk about the tensions in the job market. She established herself as "more of the same". That doesn't win votes in increasingly bad times.
Instead we have cartoon supervillains trying to pick fights with our allies in the open, and police openly shooting citizens. Pretty hard to defend that.
