Bachmann is having a go at Gingrich over Fannie Mae. Says he was taking their money as a de facto lobbyist while she was trying to stop their bad practices. Will she get traction on this? Will she peel off some Gingrich supporters or pick up enough Cain supporters to stage a comeback? Will she and Newt (and/or Paul) split the anti-Mitt vote and help propel Mitt to the nomination?
