I cannot stomach what I heard today about the Conservative Political Action Conference reaction when the president of the United States mentioned a critical vote cast by a member of the U.S. Senate.

Donald Trump didn’t mention U.S. Sen. John McCain’s name. He didn’t have to. The CPAC crowd knew he was referring to McCain’s vote on the Senate floor that sunk the GOP plan to repeal the Affordable Care Act.

Then the CPAC audience started booing. They booed a Vietnam War hero, a man who has given more for his country than I suspect anyone else in that CPAC room. They booed a man the president himself once denigrated as being a war hero “only because he was captured” by the North Vietnamese; candidate Trump then said, “I like people who aren’t captured, OK?”

Good grief! Trump simply disgusts me.

CPAC disgraced itself with that hideous display of callousness. Indeed, the president has disgraced himself as well with his own boorish behavior over this and, oh, so many other instances.

I am compelled to mention, too, that Sen. McCain is fighting for his life at this moment against an aggressive form of brain cancer.

For the president to bring up McCain’s vote against repeal of the ACA in that CPAC venue was disgraceful enough. For the CPAC audience to boo a gallant warrior who persevered more torture than anyone ever should have to endure was disgraceful in the extreme.

Shame on them.
