When Trump is speaking at a rally, he tends to be more crude. I think his choice of words for delivering his message to the people in Minnesota and the nation is Bowery bum crude, and just not necessary. Indicating that Biden was good at kissing Obama's ass...well, there are many ways that notion can be communicated, and he chose the worst way in my mind, and I am no prude.
I would not speak that way in front of my kids when they were young, what makes him think it is acceptable for him to do so with many in America? Why attempt to piss off every demographic? Parents with young kids is a demographic, and he goes out of his way to antagonize. Makes no sense.
In a state where he is 1.5 basis points based on the outcome in 2016 from winning, you would think he would polish his act and appear more presidential. NOPE! Caustic rude to the Nth degree. I find it annoying, and I do believe he drives people away that would be inclined to vote for him. He is the proverbial bull in a china shop. Lots of breakage. Getting old.
