The GOP's No. 2 in the Senate, John Cornyn, is facing electoral trouble as virtually half of Texas voters say they want someone more conservative in the Upper Chamber.
The survey, by Public Policy Polling
found 49 percent of Lone Star State Republicans want a candidate further to the right than the Senate Minority Whip.
Just 33 percent say they want Cornyn to be given the chance to seek a third term when he faces the voters next year.
A total of 62 percent said they have a higher opinion of the state's junior, Ted Cruz, than they have of Cornyn. Just 23 percent said they prefer the senior senator.
When it came to potential opponents from Cornyn's right, Gov. Rick Perry was the favored candidate. He leads the incumbent 46 percent to 35 percent in a primary, the PPP survey found. Rep. Louie Gohmert trails 40 percent to 31 percent and evangelical minister David Barton is behind 51 percent to 18 percent to Cornyn. Barton announced after the poll was conducted that he would not run despite tea party pressure.
"GOP voters are open to replacing John Cornyn, it's just a question of whether there will be a candidate strong enough to pull it off," said PPP's president Dean Debnam.
Among all Texas voters, Cornyn still leads potential Democratic candidates Julian Castro, mayor of San Antonio, 49 percent to 35 percent, and former Houston Mayor Bill White, 44 percent to 39 percent.
The poll of 500 voters was conducted from Nov. 1-4. The overall margin of error is plus or minus 4.4 percentage points.
