The author is dead on correct that the mushy, principle-less politicians are the ones to blame. They have kept running things in a "normal" fashion, or so they say. The problem is that the "normal" fashion has led us to this point. No problem solving ability, no solutions, no ideas, no guts, no truth, the death of the middle class and the rise of the corpratocracy. I would go as far as to say it's fascism with voting ballots.
The Tea Party miscalculated and probably cost the GOP taking the Senate in 2014 but they did show that they can stand as one. And that is important.
