Here is an article from American Thinker that asserts that Hamas in Palestine has been running phone banks calling people in the US to ask them to vote for Obama.

I haven't heard that before, but it would not be surprising. Hatem El-Hady, a Hamas fund raiser was working for Obama until he was identified as a member of Hamas. Robert Malley, who is pretty much an enemy of israel, worked for Obama until it was found that he meets regularly with Hamas. Samantha Power was fired from Obama's staff some time ago. Obama still has Susan Rice and Zbig Brzezinski, people who favor Palestinians. The fact that Obama has so many of Jimmy Carter's advisors working for him casts doubt on his judgement in my opinion.
