For the sake of Democratic Party cohesion, it should become conventional wisdom sooner rather than later that AIPAC is in the general sense little more than a Republican donor front.
AIPAC is the biggest source of Republican money in Democratic elections, and now they are making clear they will spend even more to defeat Democrats in November. They advocate for policies the vast majority of Democrats viscerally disagree with. No Democrat should be taking money from AIPAC.
