Senators Hillary Clinton and Barack Obama are in a fierce battle for voters.

But there is another group of voters they desperately want. These are voters they seek privately.

Houston City Council member Sue Lovell is a Texas superdelegate. Former State Representative Al Edwards is too.

He says the Clinton and Obama camps have tried to influence him, “Oh absolutely, and I don’t blame them, I would be doing that too," said Edwards.

Superdelegates could have the final say in who will be the Democratic nominee.

It depends on the numbers. Right now, it is too close to call.

So far, Obama has 1,247 delegates. Clinton has 1,204 delegates.

It takes 2,025 to clinch the nomination.

If they don’t reach the magic number, superdelegates are up for grabs as tie breakers.

“This is still rocking and rolling, fighting for the nomination how great for Texas and for the nation,” said Lovell.

It may be a great political story line, but some believe that allowing superdelegates, considered the political elite, to have the final say in the nomination is undemocratic.

“It would be a mistake on either side, Barack Obama or Hilary Clinton for superdelegates to come in and say ‘to hell with you the people, you all voted across the country we are going to change the outcome,’” said Sen. John Kerry who is a former Democratic presidential candidate and a Obama backer.

So, just who are these superdelegates?

Well, there are 796 nationwide and 35 in Texas.

They are the party faithful and Democratic members of Congress.

They could also be members of the Democratic National Committee like Edwards and Lovell.

Unlike delegates won in primaries and caucuses, superdelegates can vote for who they want. And they don’t have to make that decision until the national convention in August.

Now, if the nomination comes down to the superdelegates, it will set off more drama and raise more questions.

Questions like:

Will they pick the candidate with a majority?

Will they vote their conscience?

Will there be back room wheeling and dealing to pick the nominee?

Lovell says she is sticking with Hillary Clinton no matter what. “I am not a party, back room person. I am pretty grass roots, but my word is my word, and I committed to Hillary and for good reasons”

Edwards, who is running for the state House again, is on the fence. “Well they (Clinton and Obama) both have good attributes. I want to see Obama and I want to see Hillary.”

It is the undecided superdelegates who will make the difference.

Some political observers believe they will go with the candidate that has the most momentum.

“Why would they possibly want somebody who was not energizing, to popular, to likely to be elected by the general electorate? Those folks want to win,” said Gerry Birnberg, the chairman of the Harris County Democratic Party.

By Tuesday night, a candidate may emerge with enough momentum to grab the nomination.

That would make the role of superdelegate all but a forgone conclusion.
