"At one point, Pence mentioned 9/11 and Kaine interrupted to excitedly announce, "I was there, too, by the Pentagon!" When he wasn't interrupting, he was steamrolling through prepared paragraphs of alliterative dad jokes and scripted zingers that might have been effective -- if they weren't delivered at warp speed. And he was so wedded to his anti-Trump mandate, he often seemed oblivious. In an answer to a question about the children of Syria -- let me repeat, the CHILDREN OF SYRIA -- his response was to point out that Trump didn't pay his taxes."
Kaine came across like a rude child, hyperactive not because of too much candy, but because of too many over-rehearsed mindless talking points.
