The response to Palestine has been bipartisan, and I'd be willing to bet the sticking point for republicans on Ukraine war money has been more that they want to send more to Israel. Plus I have a hypothesis that republicans are more interested in attacking China than Russia and for the dems it's the other way around (though both obviously want to do both). Plus the republicans can spin Ukraine as being the democrat's doing so they're not as attached to achieving victory. At least not until they're in charge and have the opportunity to pitch themselves as the saviors in these conflicts, along with a change being a useful opportunity to move the goalposts for victory.
