Donald J. Trump has a peculiar way of expressing his desire to bring the Republican Party together in a spirit of “unity.”

The GOP presidential frontrunner is emptying both barrels — rhetorically, of course — into Republican Party chairman Reince Priebus for allegedly stacking the nominating process against him … meaning Trump.

Trump is angry at the way U.S. Sen. Ted Cruz of Texas managed to corral all of Colorado’s Republican convention delegates this past week. He is steaming over losing the delegate count to Cruz while “winning” the Louisiana primary earlier.

Who’s to blame? Reince Priebus, said Trump. He’s working “against” the frontrunner. He calls the chairman’s alleged tactics “disgusting” and some other pejorative terms.

Priebus’s response is simple: The rules are the rules, Mr. Trump; get over it, work with them.

I’ve got to give Cruz credit, though, for outhustling Trump — the hustler in chief of this year’s GOP primary campaign — in obtaining committed delegates. Cruz’s team comprises political pros and veterans who know how to work the system established by the party. Trump’s team, until just recently, has been lacking in that kind of experience.

However, if Trump intends to “bring the party together” should he be nominated, he’s got to learn — as if he thinks he can learn anything — that you don’t accuse the guy who runs your political party of being a political crook.

You want unity? Trump might consider working more behind the scenes, quietly and with discretion, with the chairman. He also might consider tamping down the fiery rhetoric that keeps pouring out of his mouth.

That’s the tallest of orders. It would require the once-presumed GOP nominee to change the way he does business.

It won’t happen, which is OK with some of us out here.

I’m waiting anxiously for a fun-filled Republican convention in Cleveland.
