Mayday is a PAC created by Lawrence Lessig earlier this year. The goal of Mayday is to elect members of Congress who will support public funding for congressional campaigns. When Mayday was created, its rules required that only Democrats and Republicans could earn support from Mayday. However, the organization has shifted that stance, and on May 17 endorsed Greg Orman, independent for U.S. Senate from Kansas.
See here for the full list of candidates supported by Mayday. The candidate listed on the bottom, for the Republican primary for U.S. Senate in New Hampshire, has already been defeated; the other endorsed candidates are running in the general election. Mayday has raised over $10,000,000. Mayday has endorsed the Democratic nominee in the South Dakota U.S. Senate race, even though some polls show that independent candidate Larry Pressler has more support than the Democratic nominee.
I support public funding (either monetarily or mandated free Media Exposure) for candidates for all public offices. From President all the way down to Dog Catcher. This way the rich candidates would not have the edge, and the candidate without any major funds would have a chance to get his or her message out.
This also includes allowing all ballot qualified candidates to be included in any public debate.
