Why did Pence keep ignoring rules and talk over the moderator?

Because in his way of thinking, women are 2nd class and men get to do whatever they want.

The moderator was a woman. He talked over both the moderator and Harris. That's condescending, somewhat insulting , provoking, inflaming and disrespectful. To a certain extent, Harris did this too, but not nearly as much as Pence did. Neither of them answered the last question. 

Because he's a special needs adult with developmental issues. Only a special needs adult would run on a political ticket with a special needs adult.

compared to trump he was more then polite.
