The race has been effectively tied for months. If Trump gets a bump from this debate, it will go away by the next news cycle.
A vast majority of Americans are hyper-partisans. They're not going to change their mind based on a debate. Some Americans vote based on economic conditions. Those won't change because of a debate. Their are some voters who are just idiots or don't pay attention to the news until late October. They won't even know this debate happened.
The people I see complaining the most about this debate are partisan Democrats, who'll still vote for Biden, and the MAGA crowd, who was always going to support Turmp.
