You might be interested in Ron Paul, he used to run for the libertarian party(which sounds like the closest thing to which you would agree with) and is now only a republican simply because he knows no libertarian has become president. But he speaks the most about freedom by far than all the other candidates.
Would you find a government where they would actually vote everyday on several matters any good? boring? Like if the populace as a whole ACTUALLY voted and their vote ACTTUALLY mattered all the time on every issue like the Greeks did. I see them (Athenian Greece) as having true democracy, and we are a republic where we select a few to rule over all, and hope for the best. Even though the electoral college really gets the last say so even when we do vote it's almost pointless. (so it's not actually even a republic)
