I previously posted about all the Green Party primary candidates HERE, but that field has since narrowed. Jared Ball, the professor of African-American studies and hip-hop who most likely would have been my choice, has dropped out of the race, though his name will still appear on the ballot.
Ralph Nader or Cynthia McKinney will probably take it based on name recognition alone. But you can still cast a valid vote for actor/filmmaker Jesse Johnson, environmental engineer Kent Mesplay, or Texas-based activist Kat Swift.
And since Nader only associates with the Greens when it's convenient for him, think carefully before picking him. He seems to treat the party like his personal booty call. Remember how he promised to start building the party into a viable progressive movement after 2000, then didn't even run in its primary in 2004?
