I don't disagree that politicians often pander to big money and that the way campaigns are financed forces politicians to consider the interests of those doing the financing. That doesn't however absolve citizens from voting or lend credibility to the idea that not voting somehow gives people an equal voice to those who do vote. Not voting simply puts the opposition in power, much as it did in 2000 and 2004 where elections came down to a few thousand votes.
you are caught up in this partisan theatre. Yes, for you not voting means, that "the opposition" has a better chance to win an election. Its a completely different situation for people who don´t support either of the two big parties. I still think that its worth voting for smaller candidates - if there are viable ones. Still this has absolutely no influence on who is winning an presidential election.
I also understand people who think that elected politicians will never fix the problem from inside. At this point not-voting becomes is the reasonable action. The whole argument, that people who don´t vote lose their "moral" credibility to criticize politics is nonsense. Its a technocratic top/down argument used to discredit parts of the opposition, who reject the political process.
In the end Hillary won´t take money out of politics. Her husband did the very opposite and she is also the darling of certain rich elites. Naturally she´ll appoint liberal supreme-court judges, but thats like a drop in the ocean. The right direction, but simply not enough.
Obviously she isn´t honest about this, because that would be terribly unpopular. "We need more money in politics - Hillary approves this message." That would look rather silly. So she is doing what politicians do best: Some vague promises; nothing substantial; nothing that can´t be ignored afterwards.
