America is playing with fire when it comes to Donald Trump

Also, I will not vote for anyone who supports Mr. Trump for president. Full stop.

Regarding the Jan. 26 news article “After Trump wins, congressional Republicans fall in line”:

Sen. Ted “Lyin’ Ted” Cruz (R-Tex.), Sen. Marco “Little Marco” Rubio (R-Fla.) and Florida Gov. Ron “Meatball Ron” “Ron DeSanctimonious” DeSantis (R) have all endorsed former president Donald Trump’s candidacy for president, even though he mocked them by giving them these names. Sen. Tim Scott (R-S.C.) has as well, despite Mr. Trump’s courtship of neo-Nazi white supremacists, some of whom he called “very fine people.” It is hard to have much respect for any of them when they seem to have so little respect for themselves.

Many of us knew a guy in high school who would get enormous pleasure out of making fun of other people. He would delight in his power over them — at their public humiliation and their fear. There was no way anyone in my school would have elected him to any position at all, much less one to lead our country.

And yet, the party of Abraham Lincoln is about to anoint such a cruel, hateful bully, someone with no discernible moral center, someone who seems to desire only absolute power and having everyone fear him. The ultimate question for our country is whether such a person, with the power to wield nuclear weapons if reelected, constitutes a grave and lethal threat to our country and the world. I believe very strongly that he does.
