For all the complaining about Harris’ comment (to which: ) why wasn’t Biden prepared with a better answer?
First of all, let me apologize as I do not know how to quote multiple posts in a response so I'm sorry about multiple posts.
I think the issue with Harris, at least for me, was the fact that she tried to make it seem like her attack was spontaneous when it wasn't. Both her and Booker had been talking about Biden and his relationship with some previous senators so most people knew she would bring it up. Plus, tweeting that picture during that moment during the debate and then selling it on a T-shirt the very next morning just confirmed that everything was planned. However, in her defense, I can see her having all this planned because she is an attorney.
As for Biden, I'm just guessing here, but maybe he felt that since he was the frontrunner and was in the lead that the debate would be easy for him and that he would not be attacked the way he was. He totally was unprepared for it and that is his and his team's fault. He needs to realized that everyone is aiming for him and he has to do a better job in responding and attacking.
I think it was Maher and Seth McFarlane that said that they wonder it the candidates would have acted the way they did if there was no audience. IMO, it was like a classroom. You have a student answering a question and then you have students raising their hands and speaking out of turn and yelling. Hopefully, the next debate goes smoother for all.
