"When you take a couple of steps back, you realize the astonishing success of [Obama's] movement. In the last month, every brutal guilt-by-association smear has been thrown at him and the Clintons have been reduced to hoping that Rush Limbaugh will turn out their voters. [...] He has somehow endured and survived and in North Carolina has won what looks like a stunning margin of victory. And when you look at the states that Clinton is, er, clinging to: Obama has gained among her demographic base from Ohio to Pennsylvania to Indiana. She's going backward. The Clintons will have to realize some day that their time is over. [Obama] has won this nomination, whether they try to steal it from him or not."
