I can’t watch the video right now, but did she say that she is in favor of one, or simply that it would be okay to have one?
Those are two different statements with two different meanings.
FTR, I’m in favor of one, too.
In a nutshell...
She was choosing her words carefully but said that it would not be a negative thing and not to believe those that say it would be for they would be trying to protect their candidate and in closing said that the idea is certainly something we could see happen.
