Barack Obama spanked Hillary Clinton in Maine, winning by nearly 20 points and putting an exclamation point on his weekend of dominance in the race for the Democratic Presidential nomination.

Coupled with these victories is the news that Patti Solis Doyle has been replaced as Clinton’s campaign manager by Maggie Williams. Williams was Clinton’s chief of staff when she was the First Lady.

Obama is gaining ‘mo quickly, and the move is a sign that the Clinton campaign is getting nervous with tomorrow’s important primaries looming. Getting swept in Virginia, Maryland and DC could begin a stampede to Obama, especially in the crucially important area of the superdelegates.
