Donald Trump doesn’t know about circumspection. When reticence would serve him well, he turns to his natural instinct, which is to blab, blather and bloviate.

So he happened to mention out loud the other day that he talked to Ukrainian President Volodymyr Zelensky about former Vice President Joe Biden, one of a large crowd of Democrats seeking to run against Trump next year. Specifically, he talked to him about Biden’s son, Hunter, and whether Hunter Biden had some sort of nefarious business relationship with a Russian oligarch who owns an energy country.

Trump’s big mouth has opened up the impeachment talk. Democrats are yapping about impeaching the president right now. Let’s not wait, many of them are saying, claiming that they need to do their “constitutional duty.”

Their “duty” can wait. What cannot seem to wait, though, is the president’s big mouth.

He vowed to be an “unconventional” president. Of all the campaign promises Trump made, this is one he has kept in spades. Building the wall? Replacing the Affordable Care Act? Hiring the “best people” in the White House? Pffft! They’re all down the tubes.

However, he remains unconventional in the extreme. Part of his unconventional approach has to be the way he shoots off his trap about discussions he has with foreign leaders.

Why can’t this guy, the president, ever learn that some things need not be repeated beyond the room in which he says them initially?

Oh, well. That’s just Donald.

It could sink him and his presidency. To my way of thinking, that’s not a bad thing. Not at all.
