Trump has his own polls and I bet they asked his supporters if his attacks hurt him and they said YES. simple. It’s always about the polls and his pit bull lawyers said there was no way to sue so let it go. No numbers, no lawsuit, no DT.
You know, I heard the other day that Trump really wasn't doing any internal polling, and that was one reason he got surprised in Iowa - he was going off the public polls and didn't see the internals. I don't know if that is true or if so if it has now changed, but it could explain a lot.
“Trump has his own polls “
I believe Trump has no pollsters. A few days ago in a rally he said something like, “Everybody else does the polls and I see the results. Why should I spend money if someone else is doing that?”
