Obama, Distancing Himself from Arab-Americans, American Muslims?

Barack Obama has visited churches and synagogues during his presidential campaign but, so far, he has not been to a mosque. Does his message of unity extend to American Muslims?  Many are not so sure. Would his sympathy for the Palestinians produce more even-handedness in the Middle East? Some Arab Americans don't really think so. A Christian candidate needs to quash rumors that he's a secret Muslim without offending Muslims themselves. While his hard-line support for Israel may appeal to Jews, it could turn off another constituency that's potentially crucial in several states. As Obama goes to the Middle East, we talk about political challenges at home.
