Right, but in the mean time it makes any attempt to claim "The Democrats stand for [insert policy position]" a lie, because while an individual democrat may believe in those things, the part as a whole can't agree on anything at all. They can't even align themselves on their own platform, let alone apply pressure to the Republicans. At best they're nothing but a speed break for more republican policy. You're still getting republican policy, just slower, and they can't move the needle in the other direction even if they win because they'll simply surrender in advance.

Wasting more time and more money trying to slow the rate the US collapses into a burning train wreck is an exercise in futility. The only real solution is to try and build a "coalition of the willing" to preserve what is left and the Republicans drive the rest, screaming incoherently, off the cliff they're headed for. Small scale organizing, networks to help move people to safety "underground railroad" style, to move material and finances in ways that circumvent federal control, create safe-havens that can resist federal encroachment and operate outside of federal regulation meant to break down resistance. Register some "Churches" that can provide physical plant and meeting grounds, as well as offer support services when federal support is ripped up. Build a nation within a nation.

Voting for Democrats isn't going to stop this spiral. They have no vision, no will, no unity, and zero political capital to actually create change. Sure, vote blue to slow the bleeding, if you're still allowed by next election, but as long as they're a party so big tent they have no direction at all, they're just a slower, more painful collapse.
