If you play with fire, you're likely to get burned.
Sean Hannity and Rush Limbaugh love this line of attack, since they think that everyone to the left of Jesse Helms is a closet socialist ready to surrender America to radical mullahs. And their mindless listeners actually fall for such nonsense.
But these charges bit McCain in the butt today, when some of his more zealous supporters accused Obama of being "a traitor," "a terrorist," and (of course) "an Arab." The charges were so over-the top that McCain himself was forced to defend Obama, as the following Huffington Post report describes:
John McCain was booed by his own supporters during a rally on Friday after he described Barack Obama as a "decent person and a person that you do not have to be scared of as president of the United States."
McCain was responding to a town hall attendee who claimed he was concerned about raising a child under a president who "cohorts with domestic terrorists such as [Bill] Ayers." Despite the fact that McCain and his campaign have repeatedly used Ayers to hammer Obama in recent days, the Arizona Senator tried to calm the man.
