It’s Trump’s problem. He’ll probably loose some votes for this, regardless of what you might think about profanity.
Just like two days ago. My 81-year-old father, who doesn’t really follow news/politics too much these days, has been very inclined to support Trump. He hadn’t spoken of any other candidate whatsoever. He was all but in Trump’s corner. But I was with him when the news came out that Trump was threatening to “sue” over the Iowa results. My father uttered, “man, that guy sure is showing himself off as a jerk.” The litigation thing. Totally soured my father. So these things matter. Trump almost certainly lost a primary vote there.
If I had a dollar for every freeper who starts by writing “I (or my elderly parents) were all going to vote for Trump - we had Old Betsy heating up in the driveway and were about to jump on the running board - when he said...” I’d be a rich dame.
