Sadly Crackpot, if an aspiring congressman from Thinkoutsidetheboxville, USA ran on a platform that included divestment from Israel and the support of a free and sovereign Palestine, AIPAC would swoop in and crush him. They are so entrenched in the system that they will render you an instant no hoper if you try to buck it. And if you shut up about Israel and get elected, you cannot then go on a crusade against them while you are in office, because party leaders force you to toe the line.
I wrote to my senator, the "progressive" Elizabeth Warren, at the height of the Gaza bombing, imploring her to get on the right side of history, denounce Israel's actions and be a true advocate for a sovereign Palestine. The "progressive" Warren wrote back about 3 weeks ago, with a cookie cutter line about supporting Israel's right to defend itself, while working for a lasting peace. Bullshit, essentially. And she is considered the left wing of the democrat party.
