I think the Democrat politicians, to the degree they're in line with the leftist beliefs are against Israel being for Jews because of the Biblical implications and the democrats are about subverting the Bible and going against that.

They donate and support Israel because it would be political suicide not to. Since they are an official ally ever since WW2 gave them the nation, the democrats continue as they have to, because if they suddenly said "Israel is the enemy" like Iran does, suddenly the churches in America would wake up because the left would have to explain why or otherwise justify to the nation why Israel is no longer an ally, and the left doesn't want that happening. So they pay whatever they have to pay for the purposes of maintaining the status quo. But in reality, they don't like Israel and Orthodox Jews, which is why they secretly help out Islamic nations hell bent on Israel's destruction.

Just look at Obama. He did an "apology tour" where he went to every nation in the middle east to apologize about "America's evil ways"...every nation in the middle east....except Israel. That shows how they really feel.
