Rush Limbaugh is not "endorsing" Hillary Clinton at all, of course. Rather, he is saying that it's a smart move on Obama's part to put her in his Cabinet, that he is defanging her against the possibility of running against him in 2012, that being beholden to him for the position she has held for four years will preclude her candidacy for the presidency.

"Says Limbaugh: "You know the old phrase, 'You keep your friends close and your enemies closer?' How can she run for president in 2012? She'd have to run against the incumbent and be critical of him - the one who made her secretary of state."
