Hillary Clinton rolled on Super Tuesday, racking up wins across the South powered by black and older voters. And in Texas, where Hispanics made up 31% of the electorate according to exit polls, she won over 70% of their vote.

Meanwhile, Bernie Sanders won the Democratic caucus in Colorado, where Latinos make up 15% of eligible voters, but entrance polls were not available.

HUD Secretary Julian Castro, often mentioned as a possible vice presidential pick by Clinton, cautioned that exit polls are not definitive, but lauded her strength in states across the country as different as Nevada, Iowa, South Carolina, and now Texas.

“It’s not surprising,” Castro told BuzzFeed News. “Hillary Clinton has had strong support in the Latino community in Texas and throughout the country for a very long time, and tonight’s results in Texas and her strong support from Latinos are one more affirmation that she appeals to diverse communities. It says a lot about her ability to win in November.”
