Scott Moore at Our Oregon has put together a well-written, concise summation of current knowledge regarding Americans Elect. I encourage you to read his three-part series if you are looking for a quick overview of some issues regarding this 501c4 corporation planning to run its own presidential nomination:
Americans Elect I: The Truth Behind the Corporate Scheme to Swipe the 2012 Election
Americans Elect II. A Shell Game Designed to Block Real Democratic Participation
Americans Elect III. Who’s Behind the Astroturf Organization
Moore plans to publish two more pieces, each revealing some information particular to Americans Elect’s activities in Oregon. I look forward to reading them.
