That didn’t last long, not that anyone really and truly anticipated it would.

Donald John Trump Sr. spoke briefly on Monday about the need for America to heel the wounds that divide it, about how returning heroes fighting overseas to defend us need to return to a country where all Americans love each other.

Then came last night’s campaign rally. The president donned the brass knuckles yet again and tore into: The media, critics of his responses to the Charlottesville riot, the two U.S. senators from Arizona, those who oppose his efforts to repeal the Affordable Care Act, Democrats in general, key congressional Republicans.

He tossed in a few insults along the way. Yes, the president reverted to form. Trump showed us once again — as if we needed reminding — that his version of “acting presidential” bears zero resemblance to what the rest of the nation understands that term to mean.

I’ll give him a sliver of credit at least for declining to pardon one of the nation’s most divisive lawmen, former Maricopa County “Sheriff Joe” Arpaio, who has been convicted in connection to his harsh treatment of illegal immigrants. Trump, though, did seemingly imply that a pardon was pending; so, we’ll just have to wait for that act to puncture the national mood with even more collateral damage.

Another bit of good news? No one was seriously injured outside the hall during the protests that were mounted against Trump’s speech.

We’re only seven or so months into Trump’s term as president. We have three more years — maybe — remaining before the next presidential election cycle.

Acting “presidential” used to mean that our head of state lifted our spirits, comforted us in times of trouble and appealed to our higher ideals.

Those moments are gone — at least for as long as Donald Trump occupies the Big Office in the White House.
