As Feinstein hopefully retires, some great progressive candidates are running: and about to spend a ton of money trying to win the primary against each other.
This would be a great time to experiment with alternatives. Here's my first brainstorm, imagine people posting like this:
"I gave $100 to Sister District in _______'s name because I hope you'll vote for her in the primary, but I want my money spent electing progressives in swing districts. So I hope my $100 convinces you to take a good look at _______.
...And if you support one of her also great opponents, maybe donate to a swing district in their name.
