Unfortunately, most representatives can be effectively fired by large money donors (“not playing with us? well, we won’t support your campaign.”)
So, to the extend that we vote for whoever appears on a ballot, we are voting for choices pre-selected by corporations.
Therefore, the corporations have enormous voting power. Which will not change unless we take corporate money out of politics.
I recommend Professor Lessig’s TED talk on the topic. http://www.ted.com/talks/lawrence_lessig_we_the_people_and_the_republic_we_must_reclaim.html
