Neither party represents me; and although the Republicans have exhibited their contempt for the Constitution, the rule of law, and our democratic institutions, I have no affinity for Democrats, either; Democrats are just currently the lesser of two evils.
For example, even though I'm a progressive, I oppose most firearm regulatory measures – AWBs and magazine capacity restrictions in particular; clearly that puts me at odds with many Democrats.
One must either make peace with voting for the lesser of two evils or abandon political participation altogether.
Actual, fundamental political change can happen only at the very local level, with citizens getting involved at the very local level – top-down ‘solutions’ won’t work, such as term-limits and trying to form a third party.
Ultimately, the people alone are to blame for their discontent with the current political process and all they perceive to be wrong with politics – the consequence of the apathy and willful ignorance of the voters.
