Eh, political compass doesn't necessarily mean all that much in this
I think the main ones are
the Libertarian Alliance, but I'm not sure what's gonna happen with them this election
Conservative Party, which has a mixed record of good and bad
Imgflip Unity Party (I think?), and they're kinda smaller, but they've got some good users, and maybe have potential. If you got in now and helped build it you could probably be one of the more influential members.
What exactly are you looking for in a party?
