David Brock is the President and CEO of Media Matters for America, a non-profit organization that regularly takes quotes out of context, and uses them to further his left-wing, political agenda. His popular website regularly attacks conservative analysts and pundits for using their constitutional right to freedom of speech.
After coming out of the closet and admitting he was gay, he decided to switch from conservative to liberal, and now works daily to dismantle everything he used to be, to include an admission to writing a story which he stated was not "in the interest of good government or serious journalism."
He is the author of four political books, serves on the advisory board of Democracy Radio Inc, and is a prime example of a lifetime flip-flopper.
