the donors do for sure. I think th politicians just do whatever they think will further their career. They need money to win and the donor class has a lot of money so it's all about placating the donor class. What worries me is if Bernie ultimately does fail it's going to be another whole generation of people thinking grassroots donations are pointless and giving hard earned money even to a sincere guy like Bernie is futile because of the way the deck is stacked. That drives politicians right into the open arms of the donor class. Otoh if Bernie wins grassroots funding is likely to be more commonplace and guys like Buttigieg won't go running to wine caves and compromising their own values. His father was a socialist scholar and in high school he wrote an award winning essay lauding Bernie. Pete's a classic example of someone willing to abandon their own beliefs to appease large donors.
