"I don’t see how anyone who confronts Obama’s record with clear eyes can enthusiastically support him. … How can you vilify Romney as a heartless plutocrat unfit for the presidency, and then enthusiastically recommend a guy who held Bradley Manning in solitary and killed a 16-year-old American kid? If you’re a utilitarian who plans to vote for Obama, better to mournfully acknowledge that you regard him as the lesser of two evils, with all that phrase denotes. … Keen on Obama’s civil-libertarian message and reassertion of basic American values, I supported him in 2008. Today I would feel ashamed to associate myself with his first term or the likely course of his second. I refuse to vote for Barack Obama."
