It's not about parties, it's about policies. D & R establishments are both pro-war, pro-pork, pro-Wall St, and pro-neoliberalism - essentially pro the right of the oligarchy to continue enclosing ever more of the world's wealth, for no particularly good reason.

The Rs are more pro-racism, and the Ds are more pro-identity-politics. But that's just red meat and tofu to distract the voters.

D&R fringes have more variety, with ideas that look suspiciously like social democracy on the D side, and like outright fascism on the R side.  But don't expect any serious change - or much hope - from either quarter.
