IMO I think the common thread of democrats policies... is they keep thinking if they put one foot in both camps, that they will get both camps.
So, on Gaza... they took the stance of. "let the genocide continue, send the weapons, but also send sternly worded letters".
Result: The stand with isreal crowd hears "The democrats don't support isreal". The stop the genocide people, hear they are still supporting the genocide. Result, everyone hates their stance.
Hence why musks superpac sent 2 ads, one to jewish areas pretending to be the harris campaign saying "I stand with palestine", and an ad to the muslim populated areas saying "I stand with isreal".
Same on the border, instead of announcing how BS the "Migrant crime" claims are, or how bad for everyone mass deportation is, she just said "I tried to give you everything on the border, you stopped me".
My point is, they gave enough lip service, half gestures etc... to try and convince the "don't murder everyone in Gaza" some hope that they could be worked with. IE, they delayed one shipment, Harris didn't meet with Netanyahu that one time.
Again fully agreed they were ineffective half measures, but that was enough to let the Pro-Isreal lobby go in super deep "OH MY GOD LOOK HOW ANTI-SEMETIC THEY ARE!!! I NEVER".
