I'll add some more later. As per this suggestion, consider this an open thread for any more daring souls who wish to endorse.
From NBC's Ken Strickland
North Carolina Congressman (and superdelegate) Brad Miller today will endorse Obama, according to his office.
Miller represents the 13th district, which includes Raleigh and Greensboro.
Miller met with Obama today.
*** UPDATE *** So with Miller's endorsement, here's NBC's delegate breakdown:
PLEDGED: Obama 1590, Clinton 1426
SUPERS: Clinton 273.5, Obama 261
TOTAL: Obama 1851, Clinton 1699.5
There are now 260.5 undeclared superdelegates.
Brad Miller's Statement:
I will cast my vote as a delegate in Denver for Senator Barack Obama. The decision was not easy. Senator Clinton has run an impressive campaign, and has spoken eloquently to the concerns to working and middle class American families. She is one of the great leaders of this generation
Senator Obama understands that he has the chance not just to win the election this year, but to be a great president. Americans know that Republican policies have failed because their ideas are wrong. Americans know that our government has not acted to use Franklin Roosevelt’s words, as trustees for the whole people, but have taken the side of powerful economic interests on every issue. Americans want a fundamental change in course. Senator Obama seized that opportunity.
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.
I guess none too surprising given what he said yesterday to The Hil about Clinton dropping out.
Rep. Brad Miller, a neutral Democrat from North Carolina, stopped short of advising Clinton to drop out. But the lawmaker said he is more convinced Obama will become the nominee in the wake of Tuesday’s primaries.
"I’ve expected that more strongly today than yesterday," said Miller in a Wednesday interview.
UPDATE: As noted below, Rep. Rick Larsen (WA-2) has also endorsed Barack Obama.
