Paid shills tend to have a strange effect where they polarize people in the other direction than intended since their arguments are not always well founded and honest, and they will always suffer from some form of groupthink. It's a slingshot effect--at first people fall for the farce, but soon they realize they have been mislead. It could even spoil the election and get some to vote in the opposite direction.
I think it's also pretty easy to spot these days and we're armed much better to fight it at the platform-level.
I don't think this will end well for Bloomberg, he has a long way to climb, and his name is literally associated with big money. He may have already reached saturation, and this is a dying move.
