Hell, they're so fucked up they might as well be Democrats.
I'm on the liberal side of this coin and it see it the same way you do, though I phrase it in reverse:
Democrats: The New GOP.
Democrats seem to have embraced Nixon -- his healthcare suggestions, endless war, mass surveillance. I don't really know whether Nixon was such a booster of Wall Street/banksters as the DNC, but I'm guessing so because of the economic twiddling done to pay for Viet Nam.
Anyway, our DNCGOP-monoparty really needs competition -- from both sides. I believe this so strongly I would vote for a 3d party conservative over a dem or repub any day of the week if that person had a shot (otherwise I just vote Green or for my cat).
Maybe some year, several small parties should draft up a list of things they agree on, and run a candidate who would promise to stick to that list during the term of office and try to just hold the status quo on the other things. There is an enormous intersection between policies supported by Greens and Libertarians for example. Anyway, select the one candidate and combine the vote. A few spoiled elections might make the DNCGOPtards take notice.
