Like Davy Crockett, Jim Bowie and William Travis from the Alamo, Obama thinks he's up against a "tenacious" foe. Unlike them, he insists he doesn't expect to lose.
Obama's decision to wait for election returns here was a sign of his effort to broaden his political base. Clinton won California in part on her ability to outperform Obama among Hispanic voters.
Obama cut into her share of those voters in Virginia last month and challenged her for the Hispanic vote here.
Hispanics make up about 36% of the Texas population and 25% of the state's eligible voters. One-third of the state's Hispanic voters are ages 18-29, a group that has voted strongly for Obama.
Obama began his day with a surprise visit to the Houston Livestock Show and Rodeo going after rural voters, another group that's usually difficult for Democrats. He donned a John Deere baseball cap while inspecting tractors. "I'm sort of a city slicker," he confessed.
