You knew that when Dick Cheney went on Sean Hannity's Fox News show for a sit-down interview last night, it was going to be a nonstop Obama-bashing fest.

Indeed, not only did Cheney back up the long-running Fox News theme that "Obama is a radical leftist America-hater whose plan is to weaken us and destroy us", but he went a step further -- essentially accusing the Obama administration of committing treason.

Hannity: You said that the president's cerebral approach projects weakness, and that the president is looking far more radical than you expected. I was, during the campaign, criticized a lot because I was warning, I thought, of the president's radical associations. How radical do you view him now? How radical do you view his opinions?

Cheney: I saw him, when he got elected, as a liberal Democrat -- but conventional, in the sense of sort of falling within the parameters of the national Democratic Party. I think he's demonstrated pretty conclusively now during his first year in office that he's more radical than that. That he's farther outside the parameters, if you will, of what we've traditionally had in Democratic presidents in years past.

Excuse me, but WTF?????!!!!! Neither Cheney nor Hannity explain this remark or give any example of Obama's supposed demonstration of his radicalism.

Let's see, was it Obama's decision to eschew a single-payer plan and head for a "public option" compromise on health-care reform that marked him a "radical"? His decision to increase troop strength in Afghanistan? Or maybe his willingness to scale back his stimulus package, at conservatives' behest, to the point that it failed to properly spark job growth? Maybe it was his willingness to throw Van Jones under the bus the moment right-wing talkers began circling around him. I dunno. They never tell us.

But Cheney keeps going, slagging and attacking Obama's presidency in some of the most vicious terms available -- including the suggestion that Obama and his administration have committed an act of treason.

This came when he and Hannity were discussing the upcoming trials of Khalid Sheikh Mohammad and other 9/11 terrorists in New York:

Hannity: You said in an interview that New York City is great, this trial in New York City is 'great for Al Qaeda'. That's a pretty strong statement. What did you mean by that?

Cheney: I mean that I think it will give aid and comfort to the enemy. I mean that it will make Khalid Sheikh Mohammad something of a hero in certain circles, especially in the radical regions of Islam.

Um, yeah, except of course that KSM is already "something of a hero" in "the radical regions of Islam."

More importantly, the language "give aid and comfort to the enemy" just happens to be the same language as the very legal definition of treason, as laid out in Article III, Section 3 of the Constitution: "Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort."

Cheney is essentially accusing Obama of treason.

Hannity caps it off by asking Cheney if the Obama administration "maybe doesn't believe there's a war on terror," and Cheney agreeing that it doesn't.

History has already recorded that Dick Cheney not only was one of the worst vice presidents in history just in terms of governance, but moreover one of the most vicious character assassins and ethics-deprived manipulators ever to set foot in the White House.

Now he's just adding to that legacy.
