Ross Ramsey’s analysis of Texas’s two Republican U.S. senators reminded me of a political truism authored by none other than the late President Richard Nixon.

Nixon, who essentially wrote the modern political playbook, used to say that candidates run to their extremes during the primary and tack toward the center in the general election. The president’s theory applied to Democrats and Republicans.

That might work in most eras and in most states. Not in Texas. Not now.

Ramsey, the editor of the Texas Tribune, says Sen. John Cornyn has stepped right out of “central casting” to be a U.S. senator. White hair, former judge, former state attorney general, handsome features. “Soft face.” He says Sen. Ted Cruz presents a different image. Black hair. Fiery temperament. He’s a TV camera hustler.

Cornyn is running for re-election this year. He might face a serious challenge from his right, from the tea party — aka the wacko — wing of his party. Why? Mainly because he opposed Cruz’s tactic of tying Affordable Care Act funding with the government shutdown earlier this year.

Cornyn is a virtual shoo-in for re-election. To secure his party’s nomination in the spring, he’ll have to say all the right things. He might even have to harden that soft face of his while saying them. He’ll blast the ACA to smithereens. He’ll say mean things about Democrats in general. He might even accuse the president of being something other than a true-blue American.

In another time, though, Cornyn then would veer toward the middle, saying more reasonable things. He would talk about his desire to reach across the aisle to work his “friends on the other side.” He might even mention that he is pals with a few of those Democrats.

But these days, in Texas, the Nixon Axiom no longer seems to matter. Cornyn likely will stay focused on the far right. He might even get more inflammatory as the campaign progresses into the summer and fall of 2014. That’s because so many Texas votes seem comfortable with their senators tossing bombs.

Look at Cruz’s popularity among Texas Republican at this moment. If you’re a Texas politician, all that seems to matter is whether the GOP faithful will stand with you.

All of this could play out as described here, except for one possible factor: whether Democratic state Sen. Wendy Davis’s campaign for governor gins up enough support among women angry at the GOP’s stance on abortion rights. I’m not predicting that will happen.

However, if it does, then President Nixon’s general election strategy is back in play.
