The problem is that the debate doesn’t really change much… except for low information and undecided voters. They don’t know what Trump is spewing and whether it’s a lie or not. When he makes up wild claims that Biden is unanimously declared worst president in history, they don’t know that’s a lie, or that Trump is lying about capping the price of insulin or the existence of 9 month elective abortions, etc. Trump’s confident lies actually win over a lot of undecided people who don’t do any research into the topic.
We all know that Biden is a liability. BUT WHO WILL REPLACE HIM? I don’t like the man but who else in the party can take his role? Nobody credibly challenged him during the primary. Harris doesn’t poll as well as Biden and does worse. We’re stuck with him because nobody stepped up all year or last year, and everyone who wants him to step down thinks some magic TBD savior can show up out of nowhere and magically do better. Heck, Dean Phillips tried to run for president on the exact same issues and promised identical policies just in a younger person and he lost the race badly.
We’re stuck with Biden, and likely will lose.
