I’m all giddy.

Donald J. Trump has posted a Twitter message that reads the following:

Isn’t that cool? The president is coming to Texas to campaign for Ted Cruz, the Republican incumbent who’s seeking to fend off an apparently burgeoning challenge from Democratic U.S. Rep. Beto O’Rourke.

Trump says he is “picking the biggest stadium in Texas we can find.” Let me think. I believe that would be the Cowboys’ crib in Arlington, which is only about 30 miles or so from where I live in Collin County.

This means I’ll get to attend a Donald Trump rally. It means — if it works out — that I’ll get to sit in a crowd of screaming maniacs.

Take my word for this: I won’t join them in whoopin’, hollerin’ and howlin’ when Trump spouts untruths. Oh, no. That’s not for me.

I’ll plan to be there because from what I understand these rallies are worlds unto themselves. They reportedly thrive in what can be called a parallel universe that functions right next to the real world.

Hey, I’ve made no secret of my desire to see Beto O’Rourke knock the Cruz Missile out of the sky.

To be sure, Trump hasn’t yet disclosed where this rally will occur. The state has plenty of large venues. The University of Texas football stadium in Austin also is possible, but Austin ain’t exactly Trump Country or, for that matter, Cruz Country.

The Cowboys stadium in Tarrant County, though, makes more sense.

It also gives me a chance to attend a Donald Trump, shake my head in disgust — and then declare that Beto O’Rourke would do a better job representing rank-and-file Texans than the man Trump has offered his “complete and total Endorsement.”

Oh, and such a rally would give the O’Rourke plenty of grist to remind Texans that Cruz once called Trump a “pathological liar,” someone who is “amoral” and a true-blue “narcissist.”

Is the senator a man of conviction — or is he a man of convenience?
