She did mostly but she had a few chances to go further that she missed out on.
At least she answered a specific question with a specific answer.
It's not like he asked her if Google should be broken up she answered with something else right?
He asked when she first became aware that Biden was declining, and she said Donald Trump was unstable.
He asked her that if her campaign is about turning the page, then what is she turning the page from, (when Brett said that she has been VP for 3.5 years), her answer was that Donald Trump has been running for president for 8 years.
I agree with you that she answered those questions. But do her answers seem like appropriate, intelligent, and on-topic answers to you? I mean, those are extremely basic questions which anyone should be able to answer, right? Like, they weren't even mildly complex questions that could have nuance, like the Google example you mentioned.
It's like me asking you, "Hey Shaggy, what did you eat for lunch today?" and you answer, "My car is red. It is fast. I like my car." I mean, you answered me, but you didn't say anything relevant or on point. Can you understand this?
