Artful Dodger: Considering that the likes of Bill O'Reilly and Glen Beck are by some thought of as reliable commentators on current political events.. it is a point. That they do make mistakes.. and seemingly lie on certain matters just to make their point 'bigger' does put doubt into any reasonable mind on the validity of their political bantering and the message they are fronting.

As to your contention that Obama is a pathological liar.. just because he says 'X' yet.. through having to put things through Congress and the Senate what he says becomes 'XY' is pretty normal in terms of how things work in the world of politics. It does not make him a liar, it makes him someone that has to get policies through both houses which are greatly affected by the lobbying system.
