Some background on Bachmann-looking-at-the-wrong-camera, from CNN in January:
Was Rep. Michele Bachmann looking at the wrong camera during her Tea Party-sponsored rebuttal to President Obama Tuesday night?

Still it's likely many more saw Bachmann's remarks on CNN, where it appeared the three-term Minnesota Republican was looking slightly off screen. The camera CNN took to air was actually supplied by Fox, who shot the event on behalf of all the news networks as part of the rotating network pool coverage. Fox ran Bachmann's speech at a later point Tuesday night on tape delay.
