Alan Augustson was running for the Green Party nomination...for a while, then he stopped. While I agreed with most of his positions, he pissed me off - in that I got persstantly spammed by his campaign (multiple messages per day) and he never stopped despite several attempts on my part to ask him to stop.
It'll be interesting to see if they add Cynthia McKinney to the mix, since it now appears that she's running for the Green Nomination.
