Thanks for your comment. You are the only writer--here on Medium and everywhere ese--that has suggested replacing Harris but not Biden. I'm not sure that would work, but its an interesting idea.
I have not been vocal about whether Biden should continue his campaign or not. I fear, however, that he will have another incident like the debate that will destroy the opportunity to keep Trump out of the White House.
I generally agree with you on coverage of the debate, but note that at least one channel-MSNBC--has focused a lot on Trump's night and agrees with you that Trump did a lot of lying, despite ignoring most of the questions.
