Texas is a safe state...

...for Republicans this year, but that may not always be the case. According to Chris Cillizza's blog (my emphasis): 

Whites in Texas, meanwhile, are already less than a majority. And the rapid Latino growth there has Democrats licking their chops for the day where they may have a shot at the state’s 34 electoral votes. 

Democrats are definitely a couple cycles (at least) away from competing in the Lone Star State, but that day isn’t as far off as one may think. This state experienced the biggest population growth in the country over the last decade, and two-thirds of it came in the Latino community. 

By the 2020 election, it’s quite possible that the state will feature more Latinos than whites and whites could comprise less than two in five Texans.
