In 2005, Texas joined California, New Mexico, and Hawaii as states where minority populations collectively outnumber whites, according to the US Census Bureau. In Texas and California, the second-largest group behind whites, and the fastest-growing population, is Hispanics. Nationwide, Hispanics number about 45.5 million, or 15 percent of the population. In Texas, Latinos make up about 36 percent of the population and about 20 percent of participating voters this year.
"It's the biggest pool of Hispanic voters left in a state that didn't vote Democratic in 2008," not counting Arizona, because it's Senator McCain's home state, says Richard Murray, a political scientist at the University of Houston.
For the Democratic Party nationally, the overwhelming Hispanic support presents an inviting opportunity, especially to develop party loyalty among younger Latinos, who backed Mr. Obama 76 percent to 19 percent for McCain, according the Pew analysis.
In Harris Country, which includes Houston, 70 percent of people older than 60 are Anglo, while more than 75 percent of people younger than 30 are non-Anglo, notes Professor Klineberg.
While Bush didn't carry the Hispanic vote here in 2004, he came close. He captured 49 percent of that bloc, with 50 percent going to Democratic rival Sen. John Kerry. Republicans also lost ground among Hispanics this year in Florida.
Since the advent of his political career, though, Bush found ways to appeal to the Latino community, which saw him favorably for his close relationships with Latin American leaders, his faith-based initiatives, and his ability to speak Spanish.
While Hispanics are not a monolithic bloc, many began turning away from the Republicans in Texas, and elsewhere in the US, amid the harsh rhetoric about immigration reform in 2007, says Professor Murray.
"Even in Texas you can't just be a party of white folks," he says. "Nationally and locally, the party is going to have to do some retooling."
Though the Lone Star State's spots of blue darkened on Election Day, the state remains solidly Republican (55 percent McCain, 44 percent Obama). McCain scored huge victories in rural Texas, taking as much as 93 percent of the vote in some counties in the Panhandle, helping deliver the state's 34 electoral votes to the Republicans. The statehouse in Austin also remains in Republican hands.
