Indeed. Given that about 2/3 of the public will vote for one party's candidates over the others no matter how badly the candidate equivocates or makes wrong decisions, it is encouraging that there's a fickle unaffiliated group that's willing to experiment, especially when the government is so ineffective and corrupt. And just as that same group has suffered "buyers remorse" with their election of Barrack Obama, they are now regretting their votes for new house members. These unattached voters are perhaps our best resource for preventing entrenched, long-term, one-party rule such as existed in Egypt and Mexico until recently.
An even better resource would be the existence of multiple competitive parties, but that isn't likely to occur spontaneously given our current framework, so let's hope that this unaffiliated group continues to be the thorn in the paws of the two beastly parties.
