There was one lasting lesson I learned from AOC's first election and the subsequent attempts to challenge many seats at all levels of government. That incumbents have organizations that will spend as much money as they can to stop a challenger. In the case of the Queens DA race(which is the first time AOC endorsed somebody), I seem to recall that the local democratic council had to blow their entire budget to try and stop Caban(AOC's endorsed candidate). They did manage to defeat her by 60 votes but the lesson I learned is that we should be running candidates in every single seat in every single race in every single election. Some groups like Brand New Congress have attempted this but it is tough to challenge all 435 members of the house. Unfortunately all these groups are on retreat since Biden got elected. It took a candidate like Trump to make people realize that they had hit a new low and to start doing something. Biden and the party is using the fear of Trump coming back to now suppress any dissent.

Yes the overwhelming majority will lose but it makes continuing business as usual as expensive as humanly possible. There is no way all these companies can recover every last penny if this is continually done every election. (There are small time elections happening every year so there really needs to be challengers at all levels)
