Mine suggests either UKIP or the Green party with nearly equal rating.
To be honest, that sounds pretty correct, as UKIP have some good economic liberalism and welfare policies (they propose benefit simplification, rolling up various benefits into single, non-means tested payments) which I support, vouchers for schooling and healthcare and so on. The greens are probably the most socially liberal party about if you ignore their authoritarian economic stance.
The problem is both of them are completely unvotable for me, because UKIP are far too socially authoritarian, and the Greens are far too fiscally authoritarian for me.
So it's back to the more realistic choice between the Liberal dems and the Tories, and the Lib dems have a couple of dealbreaking policies (Specifically trident replacement and nuclear power policies) that make them a no go zone.
I would love to see either a con/lib coalition (if worked right, it could make the conservatives more liberal and the lib dems more fiscally fair) or a conservative majority with a liberal opposition (with Labour as the third party) as the final result though. The big problem I see for Clegg is that half his party (the social democratic side) will never agree with a tory coalition, and the other half (the liberals for who civil liberties matter above all else) will never agree to siding with Labour. Rock and a hard place indeed.
