Are you serious? Follow the thread, It aint rocket science.  Carol thinks that if Trump BELIEVES (key word, believe) that Obama was born in outside the US, that makes him a pathological liar.

Now if he believed he was born in the US and said he believed otherwise then that would make him a liar.  Believing something that isn't true doesn't make you a liar. 

But as a general rule, Hillary supporters really shouldn't complain about someone's lying.
