How were Kaine's attack at Trump a good thing lol
Some were well placed but most of the time he went on completely random rants against Trump, spit out all sorts of accusations and totally exaggerated everything. People are annoyed by that.
If he had done such a good job at attacking Trump, more people would have given him the edge in the debate as well.
It's not because everybody carefully evaluated the debate between them without looking at this attacks against Trump, he simply didn't impress anybody with it.
