Is Tim Geithner the most politically partisan treasury secretary in history? Certainly sounds like it these days. As the government’s chief financial officer, he’s spending a lot of time firing campaign barbs at various Republicans and their policies.

Geithner has blasted Mitt Romney by name on several occasions. He frequently attacks Rep. Paul Ryan and the GOP budget. And he recently fired a broadside at top Romney economist Glenn Hubbard, who is presently dean of the Columbia Business School.
