It shows that the Democrats are so desperate and resort to lies. In the primaries they threw the kitchen sink at him,insulted his family and children, called him a misogynist, that he abused women, a racist, a clown, mentally unstable, markets were going to crash, the economy was going to tank if elected president,accused him of Russian collusion, having an affair with Niki Haley and now this porno star thing; and Trump just fights back by saying "is that all you got".
It pretty well sums it up.
