For the Democrats, it could all come down to the superdelegates and on Wednesday in Oklahoma, Senator Obama picked up one more.
The News On 6's Emory Bryan reports it's an interesting endorsement because the state's top Democrat is now at odds with the majority of democrats. They chose Senator Clinton in the primary, but on Wednesday, Governor Henry chose Senator Obama.
Oklahoma's Governor decided to cast his vote with Senator Obama despite the strong Oklahoma primary vote for Senator Clinton.
"I think the people of Oklahoma will understand that as a superdelegate and as an individual I am free to exercise my individual judgment," said Governor Brad Henry.
Governor Henry made his decision before the Pennsylvania primary.
Tulsa superdelegate Jim Frazier says the governor's decision or those of the other delegates will not have an impact on how he votes. He's still uncommitted.
"I'm listening to both of them. You never know what mistakes could be made or what revelations there could be," said Frazier.
Oklahoma has 10 super delegates and six of them are not yet publicly committed to a candidate.
Four of the superdelegates have made their commitments public, three for Obama and one for Clinton.
Several high profile party leaders, like Representative Dan Boren and Kalyn Free, remain uncommitted.
Governor Henry said he hopes the disclosure of how he plans to vote will push other delegates to take a public stand.
"Maybe I can help persuade other super delegates to go ahead and make their position known but I think it's time that super delegates finalize their decisions and make their choices known so this doesn't drag on after the primaries end in early June," said Governor Henry.
"It is what is it is and I'm not going to fret about it going on so long. The democrat candidates, both of them are getting a lot of air time and the public is getting to know them and both of them are great candidates," said Frazier.
Frazier said the public vote would weigh heavily in his decision, though he is not ready to commit either way.
