Hill's Difficult Weekend

She's about to have one:

WASHINGTON (AP) -- Barack Obama all but erased Hillary Rodham Clinton's once-imposing lead among national convention superdelegates on Friday and won fresh labor backing as elements of the Democratic Party began coalescing around the Illinois senator for the fall campaign.

Obama picked up the backing of nine superdelegates, including Rep. Donald Payne of New Jersey, a member of the Congressional Black Caucus who had been a Clinton supporter.

A big ouch to the ongoing fight. Is the cascade building steam?
