Fox played a similar video on "The Five" yesterday.
Not even Richard Nixon so blatantly misrepresented a policy and purposefully mislead the public.
Spinning and misleading rhetoric is a basic move by politicians since the dawn of time. But this is more than that. "keep your existing plan" was a key part of how it passed through the houses, and likely without it - Obamacare would have had the fate of Hillarycare.
Having said all of this - frankly I do not believe Obama knew he was lying. I believe he 100% thought it was true because he simply repeated what he was told to say by Democrat leaders. Does it excuse him for it? Obviously not - in fact it makes it worse.
