Among Texas likely voters who name a U.S. Senate candidate, 96 percent say their mind is made up.

Cruz has a 52 – 44 percent favorability rating. O’Rourke has a divided 45 – 47 percent favorability rating.

“Is the Beto bubble bursting or just hissing away with a slow leak? With less than four weeks until Election Day, Congressman Beto O’Rourke has hit a wall and remains the same nine points behind Sen. Ted Cruz as he was when Quinnipiac University polled the race last month,” said Peter A. Brown, assistant director of the Quinnipiac University Poll.

“The election is far from over, but Sen. Cruz would have to suffer a major collapse for him to lose. That is even more unlikely since 97 percent of Cruz voters say they are sure they won’t change their minds.”
