C'mon, what a lame excuse. Well then, show us that democracy works and vote for a goverment which doesn't? If I follow your reasoning, you've just demonstrated that democracy is a failure, because the US government acts in the interests of arms manufacturers since a very long time, no matter if Dems or Reps are in power.
Our democracy is clearly disfunctional. I believe corporate money has played a big role to make it worse.
