Even when you count the superdelegates:
(AP/CBS) Illinois senator Barack Obama finished a series of weekend primary and caucus contests undefeated as he bested Hillary Clinton in Maine today, according to CBS News estimates.
Obama’s victory in the Maine caucuses follow on the heels of his Saturday sweep in which he won Louisiana’s primary contest as well as caucuses in the states of Washington and Nebraska.
(…)
In the delegate chase, Obama has pulled ahead of Clinton, even when the support of uncommitted super delegates is figured in. According to CBS News estimates, Obama holds a razor-thin lead with 1,134 delegates overall to 1,131 for Clinton.
And he has a chance to build on that lead tomorrow.
