Let’s be sure to take any political prediction by Karl Rove with a generous dose of salt.

Not just a grain, mind you.

I’m not willing to bet the ranch that Donald J. Trump has “peaked,” which Rove has suggested. Trump’s peak was supposed to be at the mid-20 percentage point mark. He’s now at 30-plus percent in most Republican presidential polls.

Now we hear from Rove — who “predicted” that Mitt Romney would win the presidency in a landslide four years ago — suggesting that Trump’s support isn’t going to grow.

This election cycle has produced the most maddening series of events imaginable. I cannot remember a presidential campaign that’s been weirder than this one. Not 1968, or 1972, or 1980, or 1992, or 2000.

As a friend and former colleague told me this morning at Amarillo College, we are seeing the effects of “popular culture” on the American electorate.

I don’t know if I want Rove to be right or wrong. If he’s wrong, then Trump will get the GOP presidential nomination this summer. If he’s right, then who rises to the top? To whom do Republicans turn?

Is this guy, Rove, the final authority on these things?

His recent track record isn’t so great.
