Evangelicals vote 99% Republican, how does that explain unconditional support for Israel being the overwhelming bipartisan consensus in Washington? AIPAC and other Zionist lobbyist groups are massively influential, while equivalent pro-Palestinian groups are largely ignored. They can direct millions of dollars to primary congressmen who step out of line, or back their opponent in a swing district, and everyone knows it. The US singleminded support of Israel has cost an incredible amount of money and political capital, but it helps congressmen and senators get reelected and lines the pockets of defense contractors, so clearly it is keeping the right people happy.
