I intended to vote for Bernie in the primary because I do like that he's articulating these demands for income equality, single payer health care, more financial reform, free college, and higher minimum wage. However, the reality is that I'm so angry at the anti-Obama left at this point that I can't stand to associate with them by voting for Bernie. I also don't think Bernie has a prayer of getting nominated or (as you say) transforming the American political system, but whatever. People should feel free to vote for their ideals, not that they need my blessing to do so. I'm just tired of the senseless disappointment with the progress that's been made under Obama. To my mind we should all be fired up by how much has been done and encouraged that more can be done even without revolutionizing the system.
