Pennsylvania exit polls

Some people will believe anything other than the obvious (my emphasis in red):

"It’s clear that a sizable chunk of those questioned after they voted lied to the pollsters. The exit polls showed a 5 point margin for Hillary. In the end the margin was approximately twice that."

So lemme get this straight: people who voted for Hillary were so embarrassed by that fact that they lied to exit pollsters and claimed they voted for Obama? Does that make any sense? Or does it make more sense that Pennsylvania, a state which makes heavy use of unverifiable computer touch-screen voting, was the victim of vote fraud? The difference between five percent and ten percent is the difference between Hillary having to drop out and Hillary staying in to help McCain win in November, a goal shared by both the Republicans (who own the computer voting machine companies) and Hillary (so she can run again in 2012).
