North Carolina Rep. Brad Miller announced today he's endorsing Obama for president. Obama carried Miller's Raleigh-based 13th District with 63% of the vote in Tuesday's primary.

In a press release, Miller stated: "If Senator Obama and Democratic candidates up and down the ticket win this year and then deliver next year, we can build a consensus that will last a generation."

Fellow North Carolina Rep. Heath Shuler endorsed Clinton yesterday, a day after she carried his Asheville-based 11th District with 55% of the vote.

UPDATE: Washington Rep. Rick Larsen announced this afternoon his endorsement of Obama. This gives Obama five of the state's 17 superdelegates, with six still uncommitted. Obama carried every county in the state in its February 9 caucus.
