The poll clearly shows Cornyn is trouble, especially when you see that in the poll Sen. R. Edward Cruz (R.-Texas) has a job approval rating of 73 percent among Republicans and Cornyn 46 percent, said the pollster Doug Kaplan, who founded Gravis Marketing in 2010 and whose polls were included in the Real Clear Politics basket of polls during the 2012 campaign.
In head-to-head questions the only named individual who beat Cornyn was former Republican congressman Ronald D. Paul, who beat Cornyn 44 percent to 34 percent, but that could be a function of name recognition, Kaplan said.
“From the results of this poll, a lesser-known candidate could close the gap by embracing the Tea Party label,” he said.
The other named head-to-head results against Cornyn were: Rep. Stephen E. Stockman (R-Texas) 15 percent v. Cornyn,, Rep. Louis B. Gohmert Jr., (R.-Texas) 20 percent v. Cornyn 45 percent and Rafael Cruz, father of the Texas senator: 33 percent v. Cornyn 39 percent
Kaplan said another sign that Cornyn is vulnerable is the large numbers of respondents, who said they were undecided, those typically swing against an incumbent.
When all four men were polled against each other, Rafael Cruz came out on top with 41 percent. The others followed with Cornyn 25 percent, Paul 18 percent and Stockman with 3 percent and 13 percent unsure.
