Prior to election day, senator Bernie Sanders had been ahead in Texas polling, even in spite of Joe Biden's powerful win in the South Carolina primary, and had hopes of establishing a commanding lead thanks to the high favorability Sanders had with the Latino electorate.

[1] With the support of several last-minute endorsements like those of Pete Buttigieg, Amy Klobuchar and Beto O'Rourke, in another "surprise win", former vice president Joe Biden topped the final results with 34.6% of the vote and 113 delegates, leading over Sanders (who got 99 delegates) by almost five points, and practically leveled his loss in California.

[2] Widely seen as a blow to Sanders, his failure to win Texas helped contribute to his depleting momentum and eventual loss of front-runner status after Super Tuesday.

The 228 pledged delegates to the 2020 Democratic National Convention were allocated proportionally on the basis of the results of the primary.

Biden's strength was overwhelmingly among older people, especially whites and African-Americans in cities such as Dallas and Houston.
