Florida, a state stirring controversy for it moving ahead with its primary date before Super Tuesday on Feb. 5 and then being stripped of all delegates to the convention as a punishment by the party, saw all of its 211 delegates reseated and passed 136 to Obama.

Clinton won the Florida primary with only her name on the ballots.

Massachusetts's decision to offer Clinton 52 votes, nearly half of the total 131, grasped the convention attention.

U.S. media reports said that Clinton released her delegates gained from the primary on Wednesday, tell her supporters who were supposed to vote for her at the convention they could choose again in the roll call.

"This was such a competitive primary season," Clinton told her delegates, "I want you to know this has been a joy."

She also said that she cast her ballot as a New York Senator for Obama.

Obama is set to deliver an acceptance speech in INVESCO stadium on Thursday, which will cease his journey to become the Democratic presidential nominee and start a more tough and thorny road to the White House.
