James Talarico

The Austin Democrat, who won his party's nomination in March, led Cornyn and Paxton by margins of 3 and 5 percentage points, respectively. Both results were within the survey's margin of error.

While she didn't win the Texas Democratic nomination for U.S. Senate, Rep. Jasmine Crockett dominated the Black vote in the party's primary. Now, political experts say James Talarico must win over Crockett's voters to have a chance in November.

Joseph Locke, author of "One State Under God: A History of Religion in Texas," discusses how politics and religion have long been intertwined in the Lone Star state, why Talarico's messaging was so effective in the primary, and how it could impact the general Election in November.
