I've realized that I was the most engaged with the Democratic party when there was a faction that platformed raising the minimum wage, implementing universal healthcare, and taking measures to make housing affordable & create a federal jobs guarantee. Those stances are non-existent now, and the party truly has nothing to offer other than not being the Republicans. So what does Kamala do? Try to remake the party's image as a friendly space for Republicans who think Trump is a little too nasty. I have no interest in voting for a Diet Republican Party, and obviously millions of other people feel the same. If people want substantive change (as much as is possible via liberal electoralism), and all you're offering is, "We're the same as the other party, but not as loud about our disdain for minorities, the poor, and the women & children of Palestine!", they're just going to stay home. Awesome strategy.
