So … this is how Donald J. Trump plans to sound “presidential.”

The president flew today to Atlanta to speak to the National Rifle Association’s national convention.

He stood behind the podium and told the conventioneers about how he intends to fight for their rights as gun owners.

He said, this, too: “It could be Pocahontas. Remember that. And she is not big on the NRA, that I can tell you.”

Who is “Pocahontas” and in what context was he making that reference?

It happens to be a duly elected U.S. senator from Massachusetts, Elizabeth Warren, a Democrat who has said over the years that she has a bit of Native American heritage. Trump has challenged Warren’s assertion and has chosen to ridicule her Native American claim by referring to her as Pocahontas.

She also might run for president in 2020. Thus, he is warning the NRA that she favors stricter controls on guns, which the NRA of course opposes.

Presidents usually don’t stoop to the kind of goofy name-calling we keep hearing from the guy who occupies that post.

Still, he keeps telling us of his intention to be more “presidential.”

I’m still waiting, Mr. President.
