With such a close race in the Iowa Caucuses last night, the cable news networks had to stay live into the wee hours of the morning. This proved to be a little much for some of them, as Stephen Colbert made clear on tonight's Colbert Report. Fox News' Bret Baier lost his ability to subtract simple sums and CNN's Erin Burnett had a little trouble mastering the network's new "flick" technology. All in all, it really makes a guy miss Tim Russert's trusty white board.
