No she doesn't. It's not an important issue, she is positioned correctly, pro-Israel but desiring more restraint than Biden by the Israelis. Her Jewish husband will shield her from accusations of anti-semitism from the right when she criticizes Bibi, and Trump as the alternative (giving Bibi a green light) will force the Left to mute their criticism.
Just check opinion pools, Gaza is a non-issue for most young voters, inflation, abortion, jobs, etc. are far more important.
But it's also why the Dems should tamper down "Democracy is under attack", it may play on MSNBC but comes off like hysteria for the rest of the country. 2025 is a better avenue, with Vance tied to it
Most Americans will hate everything in 2025, and it's easy to tie that to Vance, and to a lesser extent Trump (who can credibly say he doesn't endorse it since he's never read it, he's functionally illiterate!).
