Lt. Governor David Dewhurst in Studio

CORPUS CHRISTI (Kiii News) -

Two Republicans are in a war of words as they seek to replace Kay Bailey Hutchison in the US Senate.

Ted Cruz, a former solicitor general of Texas, and Lt. Governor David Dewhurst are campaigning across the state as Tuesday's run-off gets closer.

On Thursday, Dewhurst visited the Kiii-TV studios and answered questions ranging from trade with the Chinese to his opponent Ted Cruz. He and Cruz are in a tight battle, one that polls can't agree on, as various polls have one or the other winning Tuesday's run-off.

Dewhurst said this election is critical to the future direction of the country.

"It is true, we are at a tipping point," Dewhurst said. "If we don't change Washington in just a very few years, our capital markets are going to stop lending, and that's the same thing as bankruptcy. It's 1929 all over again, but we're just that far from having the great economic expansion in our lifetime."

He said that, since he's a lifelong businessman, he can help to turn the country around. He called Cruz a Washington insider. Cruz was the state's solicitor general who argued cases for the state at the federal level.

Dewhurst has been the state's lieutenant governor for a decade, and Cruz said career politicians are not what voters are looking for these days.

"Texans are tired of career politicians in both parties," Cruz said.

Dewhurst said that, while Cruz has been in Washington working as a lawyer, he has been in Texas helping build one of the most prosperous economies in the country.

So as you've heard, the two Republican candidates are trying to prove that they are the most conservative candidate, and have the answers for what ails the country.

There is also a run-off on the Democrat side as either Paul Sadler or Grady Yarbrough will end up facing the Republican winner in November.
