As with most things, I doubt many people would be 100% one or another. Politics should never be an "Either, Or" scenario, as expressed by the Late Great Søren Kirkegaard.
I consistently vote Libertarian, though most "Republicans/Conservatives" would say I'm a 'liberal' (as if that, in and of itself, is a bad thing).
Thing is, Republicans & Conservatives are not the same thing. You can be both at the same time, but it is not a requirement.
I am very much a REPUBLICan (State's rights, limited Federal involvement).
I have conservative elements to me as well.
Same with Democratic & Liberal elements.
A regular Political Hodge-Podge.
However, I am up to date on most issue that I deem to be important.
I also see, what most people are just starting to talk about, a political middle that is not there for cooperation, but due to laziness & greed.
Most candidates on each side . . . (too bad the US only has two viable parties, not much of a choice really) . . . are not very compelling.
Of all that have entered the US Presidential election so far, there are two that I find compelling strictly due to them truly offering something different than SS, DD.
Ron Paul from the Republican Party - A Libertarian that runs with an (R) next to his name because he recognizes how frightened the American public is of change. A bunch of neo-phobes to be sure. Very little chance to win the Republican Primary, though he has come in second (according to non-scientific polling) in each of the first two Republican debates.
Dennis Kucinich from the Democratic Party - the only Democrat that is not afraid to offer something different. He has even less of a chance than Ron Paul. Him & Edwards are certainly the most honest of the Democratic bunch.
ETA: Wait a second, I picked Libertarian (and you said you did also, ryushi) yet it is showing one for Democrat & one for Libertarian?
