The job of a presidential candidate is to convince people to vote for them.
Hillary could not, and barely seemed to try. She ran a campaign that consisted of pointing at Trump and saying “C’moooooooon!” Watch the VP debate, for the greatest distillation of it. Pence is repeatedly asked challenging questions. Kaine interrupts them with “TRUMP SAID IRRELEVANT TO THE QUESTION BUT BAD THING! I DEMAND YOU REPUDIATE THAT!”
I saw one comment about her that said “Hillary may not be able to communicate her positions, (As if that should matter,)”
That blew me away. As if that should matter? It’s a democracy! How can you dismiss the idea that a voter should be able to judge a candidate?
