I'm a rabid left-wing radical, and apparently a fiscal conservative as well.
This is why I can't stand the fake left-right divide, it's trying to project a high dimensional thing down onto a one dimensional space and it's just too coarse.
Furtunately some people are taking a stand against it. For the UK bigots/xenophobes tended to the conservatives so it was always seen as a right wing thing. Now we have the UKIP which is the bigot's leftie party.
While I jest, I'm seriously hoping we end up with a multiparty government. We've already got 4 (juuuuuust---though the Green's one MP barely counts), but more parties is a better opportunity to represent the political spectrum. It's likely we might end up with Consrevative, Labour, Lib Dem, Green, UKIP and SNP this time round, which will be historic.
A Libertarian wants a government that doesn't defend rights, but defends contracts.
Depends which libertarian. The internet is infested with internet-libertarians who think all govenment==evil, and you should enforce contracts via a private army.
