DEFINING CORRUPTION DOWN…. In October, Rep. Darrell Issa (R-Calif.) told Rush Limbaugh he considers President Obama “one of the most corrupt presidents in modern times.” He didn’t even try to defend such a claim, and looked pretty ridiculous making it.

On Sunday, Issa tried again, insisting that the Obama administration, not the president himself, is “one of the most corrupt” in years. When he tried to back this up with some vaguely-specific evidence, Issa’s argument quickly crumbled — the alleged corruption didn’t point to anything corrupt.

Yesterday, Issa gave this yet another shot, deciding to give a new definition to the very idea of political corruption.

“I think people misunderstand the meaning of the word corrupt, and obviously, CNN does. ‘Corrupt’, or ‘corrupted’ or ‘failure’, it’s no different than a disc drive that’s given you some bits that are wrong,” Issa said on CNN.

Issa continued, “I have never said it’s illegal. I’ve never made any of the statements that are often said on CNN that implied wrong-doing of the president at a criminal level….”

Yes, we’ve reached the point that in the 21st century, the chairman of the House oversight committee — who enjoys expansive oversight authority over the White House — needs to parse the meaning of the word “corruption” on national television.

Worse, he thinks the administration is “corrupt” the way a computer disk is.

That there are voters and media outlets that take these clowns seriously continues to amaze me.
