In an interview with the New Yorker, Texas Republican senator-elect Ted Cruz warns that if his party doesn't make inroads with Hispanics, his red state could turn blue: 

“In not too many years, Texas could switch from being all Republican to all Democrat,” he said. “If that happens, no Republican will ever again win the White House. New York and California are for the foreseeable future unalterably Democrat. If Texas turns bright blue, the Electoral College math is simple. We won’t be talking about Ohio, we won’t be talking about Florida or Virginia, because it won’t matter. If Texas is bright blue, you can’t get to two-seventy electoral votes. The Republican Party would cease to exist.

Only 11 percent of Republicans’ total vote came from non-whites in 2012. The Fix has more on the GOP's growing demographic problem, and notes that Latino voters also appear to be shifting on gay marriage. 

Cruz, a Cuban American, beat Lt. Gov. David Dewhurst in a primary runoff earlier this year with help from conservative groups.
