Obama is a continual, continuous, and compunctionless liar.
His biggest problem is that, unlike impeached and disbarred Wm. Blythe (Clinton) who is remarkable at lying, Obama's lies appear more easy to spot.
I'll suggest that Marxist Obama has about four mannerisms that "tell" his mendacity.
The biggest of which is that Obama gets unusually matter-of-fact, puts on an aristocratic (or defensive) air, and speaks in more halting terms than usual.
(Actualy he is much less fluid than Dubya, his predecessor. People think that Marxist Obama is a good speaker, but really he just enunciates consonants fully- - especially the "s", and he has the deep basso voice of a chain smoker).
Where impeached and disbarred Blythe (Clinton) would look the camera squarely in the lens, IIRC Marxist Obama has difficulty with sincere eye contact when lying. My recollection is that he looks away and down when lying when cornered. Perhaps a psychological expert could make sure that I'm telling the truth on this one.
Like all malignant narcissists, Marxist Obama is a blamer. And, he instinctively covers his lies with blames, as if that would convince us. (For example, Marxist Obama lied when he blamed a "broken system" for refusing to play by the public campaign financing rules, and blamed ...Republicans!)
It's not just that Marxist Obama has no trouble lying, lying seems wired into his DNA.
Here's a guy that you would trust with nothing, absolutely nothing; and he's our president and commander in chief.

But what to do about it?
