Eyewitness News takes a look at the two men -- Grady Yarbrough and Paul Sadler -- vying for that nomination and the messages they hope will eventually lead them to Washington, D.C.
Ted Cruz is running for Senate. It's well documented that he's taking on Texas Lieutenant Governor David Dewhurst. They've been seemingly ubiquitous in their efforts to win the Republican nomination. But whoever wins on Tuesday isn't finished campaigning. He'll take on one of these two men to win the seat in November.
"I think the race is going to based upon ideas, not on money. I think I have some ideas to get our economy going," said Yarborough.
"Our ability to deal with our national debt frees up money and for paying back that trust fund. If we can't pay back that trust fund then we have to look at entitlements. We don't have a choice," Sadler said.
Here are the two men debating each other in Dallas, with Sadler even acknowledging the lack of attention dating back to before the primary vote in May.
"All of the media and all of the attention has been focused on the four Republican candidates," said Sadler.
Sadler is from Henderson, Texas, near Tyler. He's a former state representative and licensed attorney who now heads a pro-wind energy non-profit.
Yarbrough lives in San Antonio, has a master's degree in education from Prairie View A&M and taught school for 50 years.
"They're irrelevant," said Jon Taylor, Chair of the Political Science Department at the University of St. Thomas. "It's rather sad for Democrats, for a state that had an amazing history of Democratic U.S. Senators, for the Democrats to have essentially punted on the race this year."
While neither Yarbrough nor Sadler would likely say their punting, it could take a Hail Mary for them to score a victory in November.
We did reach out to both campaigns for comment today, but did not get a response from either.
