Former Vice President Joe Biden has a commanding lead in Texas over any of his Democratic rivals in the race for the White House and does the best in a hypothetical head-to-head matchup against President Donald Trump, according to a new poll released by CNN on Wednesday.

Biden was the choice of 35 percent of the 327 likely Democratic primary voters in Texas who were polled. U.S. Sen. Bernie Sanders was in second place with 15 percent. Elizabeth Warren was third with 13 percent.

Although South Bend, Indiana, Mayor Pete Buttigieg has been surging in Iowa, the Texas poll shows he’s still the choice of just 9 percent of Texas primary voters.
