I don't have a litmus test, I'm just sick of Democrats who trade away all of our economic rights such as collective bargaining, progressive taxation, not allowing money to be treated as speech for political purposes, or really any of the priorities FDR laid out in the second bill of rights, in exchange for "social progress", most of which just gets rolled back when the Kochs spend enough money to get their political lackeys into power. The only way out of that death spiral that I see is a political party that prioritizes economic rights and freedoms above all else. I want that to be the Democratic party, but every time anyone comes along on the Democratic ticket who wants to prioritize those issues, people like you call them racist and distract from what they're trying to accomplish all because they're not prioritizing the issues you think they should.
