If the stakes are so high, Trump should not throw away votes by calling a woman "horseface", even if some of his supporters find it entertaining. Trump's comment will cost the GOP votes in House and Senate races.
You do realize that for the last couple of weeks she has been on CNN talking about Trump's PENIS?
Complete nonsense. He tweeted this so that everyone would SEE that a defamation lawsuit by her against him was thrown out.
Now the beauty is that MOST will think this is the NDA lawsuit that is still active.
So he said "horseface" to draw attention to the tweet which many will now see that otherwise wouldn't because pearl clutchers will say "he shouldn't say that about a woman".
Some of those people will be shaky republicans or shaky independents who were spooked over the (fake) NDA.
You posit that it's going to be harmful than good because you must believe that people are going to sympathize more with A PORNO ACTOR who got fame ONLY by lying about President Trump then with President Trump himself.
