This will be fun to watch.

In an unexpected move late Monday just before the qualifying deadline, Rep. Steve Stockman (R-TX) jumped into the Republican primary against Sen. John Cornyn (R-TX), setting up what will be one of the most-watched tea party v. GOP establishment clashes of the 2014 cycle.

Stockman, one of the more outspoken conservative members of the House of Representatives — he once threatened impeachment of President Obama over using an executive order to try and reduce gun violence — announced his candidacy for Cornyn’s seat on Monday in an interview with WND.com.

“We are extremely disappointed in the way he treated his fellow congressmen and broke the 11th commandment and undermined (Sen.) Ted Cruz’s fight to stop Obamacare,” Stockman told WND.com.

Stockman filed his candidacy for Cornyn’s seat at 5:45 p.m. on Monday, just before the 6 p.m. filing deadline, according to the Houston Chronicle.

Those of us in the real world know that Mr. Cornyn is one of the stalwarts of the right wing, so getting a challenger who doesn’t think he’s right wing enough will be a hoot.

Popcorn futures are looking really good.
