Previously undeclared superdelegate Rep. Brad Miller, D-N.C., said that he would cast his vote at the Democratic convention for the Illinois senator.
Miller made his decision after meeting with Obama in Washington today.
"Senator Obama understands that he has the chance not just to win the election this year, but to be a great president," Miller wrote in his announcement.
Read Miller's full statement below:
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.
