I get that Donald J. Trump is proud of his daughter.

Moreover, I also understand that he wants her to succeed to the fullest.

But for the life of me, I do not get why the president insists on using Twitter in the fashion he uses it. Now he says Nordstrom is treating Ivanka badly and he has taken to Twitter to make his feelings known.

The president has a full plate of issues to consider. You know, things like war and peace, the economy, getting his Cabinet picks confirmed by the Senate. Small stuff, right? Um, no. They’re real big!

So why is the president taking on a department store company because it no longer wants to market Ivanka Trump’s brand of products?

Honestly, I am tired of commenting on this baloney. I feel I must protest, given that the social media maven happens to be the president of the United States of America, the guy who governs the country of which I happen to be a taxpaying citizen.

Someone coined the term “diplomacy by Twitter.” That’s a dangerous practice. The president shouldn’t use this social medium to communicate foreign policy. He shouldn’t use it to criticize federal judges. He shouldn’t use it to boast about crowd sizes and poll numbers or blast those who dispute them.

The presidency is an office that compels maximum respect and dignity. Its current occupant clearly — in my mind — is denigrating the decorum that this high office commands.
