TEXAS — As candidates are always quick to point out, the only poll that matters is on Election Day. But with just over three months to go, two polls show the race between Ted Cruz and Beto O'Rourke in a dead heat.

According to Quinnipiac University, six points, 49-43, are all that separates the Republican incumbent from his Democratic challenger. Those results are closer than a poll released by the group in May, which showed Cruz with an 11 point lead.

Meanwhile, the nonprofit, nonpartisan Texas Lyceum 2018 poll shows Cruz with a mere two point lead over O'Rourke.

Among likely voters, Republican incumbent Cruz carries 41 percent of the vote, compared to Democratic challenger O'Rourke's 39 percent. Nineteen percent of voters say they're undecided.

Even before the most recent Lyceum poll was released Cruz's camp voiced its skepticism over the group's past polling.

Tonight at 7, we talk to the Lyceum poll's research director to discuss the results, the criticism and where the other statewide candidates stand.

Texas’ Senate District 19

Republican Pete Flores and Democrat Pete Gallego are headed to a runoff in the race for Texas’ Senate District 19.

Flores received 34 percent of the vote with Gallego at 29 percent in Tuesday night’s special election.

State Rep. Roland Gutierrez came in third place with 24 percent. The remaining five candidates all received less than 3.5 percent.

The seat was up for grabs after former State Sen. Carlos Uresti resigned last month. He was found guilty of fraud and sentenced to 12 years in prison.
