John Podesta, former Clinton ally and confidant, built the Center for American Progress — which runs Think Progress — into a potent, misleading and devious message machine in favor of the Obama administration.

Podesta is stepping down, and is being replaced by Neera Tanden, a former Obama campaign official.

Tanden has been Chief Operating Officer of CAP, so this doesn’t represent a sea change.  But is does emphasize how CAP and Think Progress are nothing more than mouthpieces for the Obama campaign.

Tax exempt mouthpieces, of course, arguing for tax increases on the “rich” while, of course, acting fully within the law as a “nonpartisan organization under section 501(c)(3) of the Internal Revenue code.”
