Most Texas Democrats say they'd prefer former U.S. Rep. Beto O'Rourke to abandon his campaign for president and instead take on Republican incumbent U.S. Sen. John Cornyn in the 2020 Senate race, a new poll released Wednesday shows.

Sixty percent of about 400 Democratic and Democratic-leaning voters polled by a Quinnipiac University said they would prefer to see a O’Rourke take on Cornyn. The poll surveyed 1,159 voters overall and had a margin of error of plus or minus 3.4 percentage points overall and plus or minus 5.8 percentage points for Democrats and Democratic-leaners.

Yet O’Rourke was still preferred over most other Democratic candidates for president. Former Vice President Joe Biden led the pack as the top choice for 30 percent of Texas Democrats polled. O’Rourke was behind him with 16 percent, followed by Vermont Sen. Bernie Sanders with 15 percent and Massachusetts Sen. Elizabeth Warren with 11 percent.

California Sen. Kamala Harris and Julián Castro, former San Antonio mayor and HUD secretary, each claimed 4 percent, and South Bend Mayor Pete Buttigieg took 3 percent.

A change in course for O’Rourke, or even Castro, would not be entirely unexpected to Cornyn, who had a 44 percent approval rate among those polled by Quinnipiac.

“I don't think it's out of the realm of the possibility that that could happen,” Cornyn told the Dallas Morning News in March. “The filing deadline is December the 9th, I believe. So my expectation is that perhaps Beto, perhaps Julián Castro or others who have indicated that they're running for president — if they're not getting a lot of traction, then obviously it's very easy to pivot into the Senate race.”

In the latest sign that Texas’ reliably Republican status is at risk after one of the most competitive midterm elections in years, voters in the poll put Biden ahead of President Donald Trump by a four-point margin, 48 percent to 44 percent. The positive numbers for Biden could be an indication that Texas won’t be the shoo-in for Trump that it’s been for Republicans in decades past.

GOP candidates have won Texas in every presidential election since 1976 and in every statewide election since 1994.

But in the 2018 midterms, Texas Democrats managed to flip 12 state House seats, two state Senate seats and two congressional seats — one of their best showings in over a generation — leading them to dream about a purple Texas in 2020.

Trump still has a slight edge over all the other top Democratic presidential candidates, including a 48 to 45 percent advantage over O’Rourke, a 46 to 45 percent advantage over Warren and a 47 to 44 percent advantage to Sanders.

Similarly, he held a 46 percent to 44 percent advantage over Buttigieg, a 47 to 43 percent advantage over Harris and a 46 to 43 percent advantage over Castro.
