So, why are you having debates before conventions?
What reasons if any was given?
Conventions are fun. There is an article on the Secular Web about how much fun atheist conventions used to be. People like hotel parties a lot. That's why.
There is no downside to having a convention. Public Relations won't suffer at all. The leaders of the USA are confident in the system. Hotel parties are really important to a lot of moneyed people. Nobody who matters cares or has any other ideas.
These people still think that TV ads are an appropriate expenditure. This is how we can be sure that it genuinely does not matter who the human avatar of President of the USA is. Project 2025 is a done deal.
