Capitalism Magazine has published this four-part article on Barack Obama -- its the strongest attack-piece that I've read so far. A very compelling read for any American. I strongly recommend it.
Barack Obama: The Messiah of "Change" (Part 1 of 4)
Barack Obama: How a Political Non-Entity Rose To Power (Part 2 of 4)
Barack Obama: Obama's Political "Angels" (Part 3 of 4)
Barack Obama: Anti-Capitalist Money Machine (Part 4 of 4)
