Donald Trump has become tweeter in chief.

His latest foil is another former prominent politician, a guy named Arnold Schwarzenegger. The two men connected by a reality TV show, “Celebrity Apprentice,” have been tweeting back and forth for a couple of days now.

Honestly, it is so damn “unpresidented” — to borrow a term — that it’s driving me batty.

Trump is telling us how “Apprentice” ratings have tanked since he left the show to become, um, president of the United States of America. Arnold — the current host of the show — has responded with a seemingly tongue-in-cheek attack on the president, suggesting the two men switch jobs; if only the U.S. Constitution would allow the Austria-born Schwarzenegger to do the job that Trump now holds.

I know this plea will fall on deaf ears. My Trumpkin friends who read this blog will scoff at me; the anti-Trumpkins out there might express some sorrow for my persistence.

Still, this activity by the president of the United States is so unbecoming of his office. I get that Arnold bears some responsibility as well, given that he once was a consequential governor of the nation’s most populous, wealthiest state — and who once was married to a member of two of the nation’s most prominent political families: Maria Shriver.

Maybe I should just heed my own advice and ignore this ridiculous behavior. I should stop commenting on it with this blog.

I guess I have to acknowledge that I am doing Trump’s bidding by calling attention to it, no matter how negatively I feel about it.

There, I just did. I still don’t like it.

Put down the Twitter device, Mr. President. You’ve got many more infinitely more important matters to occupy your waking hours. This is no way to “make America great again.”
