FROM CNN's Jack Cafferty:

Ever since Super Tuesday, Barack Obama has been outscoring Hillary Clinton big time when it comes to picking up support from the superdelegates. The Wall Street Journal suggests he's close to taking the lead, and that if he doesn't stumble badly in Indiana or North Carolina next week enough of them will break his way after June third to give him the nomination.

He's won more states, has more popular votes, is a much better fund-raiser–very important consideration–and has shown he can appeal to Independents and Republicans. Piece of cake. Just run out the clock and get ready for McCain.

And therein lies the problem for Barack Obama.
