there's a big difference between obama saying "i'm going to do this and this and this" and then not doing any of it, and somebody being specifically selected by a committee and then abandoning it. i think the point was kind of danced around: it's a last straw for democracy. if candidates are willing to be contemptuous on such a brazen level, it's time to grab the pitchforks.
but, i don't think this is the answer.
there's the old jeffersonian cliche about an educated electorate, and it's really exactly what you're coming up against here. those lies don't fool me. they don't fool either of the people in the video. why do they fool so many?
but, this is a really fundamental issue. the reality is that if our voters can't be bothered to run a fact check in the internet era then we simply can't have a democracy. the masses should be able to look at the propaganda and scream "bollocks!". and, that's why i actually don't believe in restricting financing: if this is the determinant, the society can't be a democracy, anyways.
you should be focusing more on reforming the education system. you do that, this negates itself on it's own - and we can start talking about democracy as more than a naive abstraction.
