I feel like Israeli aid, while vastly more salient than it used to be, is still mostly salient as a left-of-center wedge issue, otherwise being about as salient as your average major foreign policy issue - ranking just under the least salient domestic policy issue, which ranks just under the most minor personal quality of any candidate, which ranks under the current state of the economy, which ranks under the current perceived state of the economy. Wow, that's way too many times to use "salient" in one sentence.
And for the record, I'm not arguing about how much people should care, just how much they do.
