I am quite certain that Donald John Trump is going to be pretty steamed when he catches up with the events of today.

The president was pointedly not invited to the late Sen. John McCain’s funeral. He and McCain had differences that went far beyond policy matters. Trump disparaged McCain’s heroism during the Vietnam War, when he was held captive as a POW for more than five years. When the senator became stricken with the brain cancer that took his life the other day, Trump continued to harangue against the senator’s “no” vote to repeal the Affordable Care Act.

McCain took it personally.

The senator did invite Trump’s two immediate predecessors: Presidents Obama and George W. Bush. Both men delivered touching eulogies honoring the life and public service career of the senator.

Both men also delivered messages in tribute to Sen. McCain that could not be mistaken for what they were intended to do: to remind us of the pettiness, petulance and small-mindedness that has infected the White House since Donald Trump became president.

President Bush said McCain didn’t tolerate “swaggering despots.” President Obama praised McCain for calling on Americans to be “bigger” than the politics that are based on “fear.”

“So much of our politics, public life, public discourse can seem small and mean and petty, trafficking in bombast, and insult, and phony controversies, and manufactured outrage,” Obama said at the National Cathedral.

You know who the 44th president had in mind. So does the current president of the United States.

But, hey … if the shoe fits.
