Guess who isn't listed on the ballot in Texas

You wouldn't believe me if I told you, so see for yourself.

From the Barr campaign:

Atlanta, GA - Bob Barr is slated to be the only presidential candidate on the ballot in Texas after Republicans and Democrats missed the Aug. 26 deadline to file in the state.

"Unless the state of Texas violates their own election laws, Congressman Barr will be the only presidential candidate on the ballot," says Russell Verney, campaign manager for the Barr Campaign and the former campaign manager for Ross Perot. "Texas law makes no exceptions for missing deadlines."

I would think that filing for the Texas primary guarentees that a candidate will appear on the primary if he or she wins the nomination. But if the Democratic and Republican parties were supposed to file on behalf of their candidate, yet failed to do so, does that mean Barr will be the only candidate on the ballot? If McCain and Obama are to be included, why aren't they listed on the Texas SOS site?

Personally, I'd hate to win a state on a technicality like this. Even minor party candidates like McCain deserve to be included.
