If I were a betting man — and I damn sure am not — I might be inclined to think that Sen. John Cornyn is facing a serious challenge to his once-storied congressional career.

He’s going to face Texas Attorney General Ken Paxton on May 26 in a runoff election for the Senate seat Cornyn has occupied seemingly since The Flood. Why the gloomy outlook?

Cornyn finished first in a three-way Republican Party primary, winning 42% of the vote. Paxton finished second with 41%. Third place went to U.S. Rep. Wesley Hunt, who collected 13%.

Paxton and Hunt both paint Cornyn as a RINO, a ridiculous assertion on its face. If there is a more dedicated Republican in the Senate than Cornyn, I do not know who that would be. Indeed, Paxton and Donald Trump, his bestie in the White House, are the real Republicans in name only.

So, with the field narrowed to the top two GOP finishers, it falls on Paxton to seek Hunt voters to close the narrow gap between him and Cornyn. If the Hunt crowd is as MAGA gullible as I suspect they are, Paxton should have little trouble rounding up the support he needs to send Cornyn packing.

And what about Paxton? The guy is ethically challenged, to state the obvious. He was indicted early during his time as AG by a Collin County grand jury of securities trading allegations. He was supposed to go to trial long ago, but skated free of that episode. Several key legal aides quit the AG’s office and accused Paxton of corruption. The Republican-dominated House of Reps impeached Paxton, who then avoided conviction in the Texas Senate when Republican senators declined to follow their House colleagues’ lead.

If Paxton should manage to win the runoff, he will face a seriously rising star in the Texas Democratic Party, state Rep. James Talarico, who I will guess is dying to run against the ethically challenged AG.

We have just witnessed the opening act of a yearlong political drama. It’s going to get a whole lot rougher as we move on through the year. And if I were running the Democrat’s campaign, I just might be drooling at the chance to take on Ken Paxton.

First things first. Paxton has to win the GOP runoff. Here’s hoping for a donnybrookl
