Initially, I was going to write a long, systematic critique of this post but I think it is better to just read the following words aloud while watching this video. Then they might make more sense (emphasis mine [as if the two are mutually exclusive!])... and really, given the recent Court decision, I am already nostalgic for this level of cynicism!
This is not to say that we should always capitulate to powerful interests, but that these interests will always have a say in government and that our system of lobbying is an alternative to much less desirable arrangements. Pretending that if Obama were more liberal that the government would suddenly have to tools to oppose these interests is wishful thinking. These problems are systemic and not attributable to any individual.
