No thanks, Dems have proven they don't care about primaries. They don't care about the working class. They don't care about solving problems or even preventing fascism.
So they're a failure of a party, one that has no democratic route to being fixed.
Vote third party. Down ballot, up ballot, everywhere. People forget we had fptp and a similar duopoly when the Republican party was invented, that broke the duopoly and formed a new one. It's not an excuse.
