I just wanted to point out that there's no direct link to donation money and campaign funds, and it's only a part of the bigger picture of the strategy - the time and energy wasted, the infighting amongst leftists, and the unification of their voting bloc.
It's why I always advocate for people to vote in local politics. Because Republicans sure do, and so much of this stuff starts at a local level and needs to be stopped at a local level long before it gets to the presidential race. They're the ones voting people to school boards to ban books from schools and such. We need to stomp it out at the source rather than fighting fires after they're already started.
