Kerry did vote for the Patriot Act, the No Child Left Behind Act, and the war in Iraq, even though he constantly trashes the Patriot Act, the No Child Left Behind Act, and the war in Iraq. He voted against the Defense of Marriage Act, which limited marriage to a man and a woman, but he now says marriage should be limited to a man and a woman. (Although he also points out that he once attended a gay wedding.) And those are just the better-known issues on which Kerry has "evolved."
