Obviously you are assuming that I'm pulling my statements out of thin air (or some other place where the sun don't shine :D ).
Here's a paper from Princeton University that essentially says that public opinion as almost ZERO effect on US policy:
Also it should be noted the paper contrasts public opinion to 'organized interest groups':
> Our third and fourth theoretical traditions posit that
public policy generally reflects the outcome of struggle
among organized interest groups and business firms.
But in a number of cases organized interest groups are representative of a significant sector of public opinion (the NRA being one such example, or the ACLU is another).
Even those people who aren't so consistent in their voting just vote for whoever the advertising tells them to, which favors the most well funded and thus most corrupt candidates.
