To your exact point about us being biased because we pay more attention to politics. I think people who wait till 72 hours before to decide don’t do so because they are politically ascended and have chosen to wait until 3 days before to make sure all of the facts are in on either candidate’s political positions so they can fill out their voter decision matrix to calculate the exact candidate for them.

Of course not. They wait until 72 hours or less because they haven’t given a single thought to the election and are just going to vote based on their gut feeling at the last minute. Unless a debate happens the day before election day (I want to see that happen lol) it’s in and out of the political consciousness too fast to matter. The same voters who don’t make up their mind until 72 hours before are the same voters who debates don’t affect in the slightest. The venn diagram overlaps.

To my initial point. The reason for a debate would be the old school reason of actually having the candidates posing hard-hitting good-faith questions to each other to show why their side has thought about the arguments and the issues more. That hasn’t happened in decades though of course.
