A poll released Friday by the University of Texas and The Texas Tribune found that the senator from Vermont received 24% of the vote from Democratic primary voters in Texas, a 12-point jump from a similar survey in October.

Sanders had strong finishes in the first two states to vote, finishing a tenth of a percentage point behind former South Bend, Indiana, Mayor Pete Buttigieg in Iowa and first in New Hampshire.

Following closely behind Sanders in the new poll, former Vice President Joe Biden earned 22% of support among Democrats in Texas. Biden, once seen as the front-runner, had disappointing results in the first two states to vote, coming in fourth in Iowa and fifth in New Hampshire.

Falling behind in third, Sen. Elizbaeth Warren of Massachusetts received 15% of support among Texas Democrats after finishing third in Iowa and fourth in New Hampshire. Former Michael Bloomberg, who skipped Iowa and New Hampshire, earned 10%.

The poll also found that 80% of Republicans in Texas would "definitely" vote to reelect President Donald Trump, with 6% saying they would "definitely not."
