Barack Obama is on course to win the most delegates in the two-step Texas election, if he continues to hold his double-digit lead in the prolonged caucus count and if the results are upheld in the latter stages of the state's arcane nominating process.

Hillary Clinton scored a high-profile win in the first stage of the Texas contest -- the March 4 primary, held to allocate two-thirds of the state's 193 pledged delegates. Clinton took 65 delegates to Obama's 61 delegates in the primary.

But the caucuses, or precinct conventions as they're called in Texas, were held immediately afterward to allocate to remaining 67 delegates. They broke to give Obama a stronger lead than Clinton had in the primary.

Preliminary results, which reflect 41 percent of precinct caucuses, show Obama leading 56 to 43 percent, according to Texas Democratic Party spokesman Hector Nieto.

Results are unofficial and incomplete, and all the results aren't due until March 29. But Nieto said if the trend holds, it's fair to assume Obama will win the caucuses by more than four delegates, and in turn come away with more delegates than Clinton overall.

The Texas Democratic Party will not project a winner. As in other states, the delegates are selected in a multi-step process.

The first step was the March 4 precinct conventions, which chose delegates to the March 29 county/state Senate district conventions. Those conventions will choose delegates to the June 5-7 state convention, which will finally elect delegates to the national convention. Delegates have the ability to shift their support during that time, though they do so infrequently.

"These are unofficial results and the results can change at the very end," Nieto stressed.

Further complicating matters, the party on Monday gave up its effort to produce a public tally of the precinct caucus count that reporters had requested, saying county chairmen decided to stick to the rules, which don't require publication until they are official.

The Associated Press shows Clinton and Obama still tied in Texas at 92 delegates each, with nine left be allocated.

But if the trend continues in the caucuses, Obama would likely take the lead in the end.

The Houston Chronicle projected Obama would end up with 37 caucus delegates to Clinton's 30.

That would put the final pledged tally at 98 for Obama, 95 for Clinton.
