Singer Amanda Palmer, who knows a thing or two about raising money, is helping Harvard professor Lawrence Lessig in his bid to create a “super PAC to end all super PACs.” Monday, Palmer, armed with a ukulele, is doing an interactive online conversation/concert on www.wizeo.me. The performance is a benefit for Mayday PAC, a group begun by Lessig and GOP media strategist Mark McKinnon in hopes of raising $12 million that could be used to target candidates opposed to inhibiting the political influence of wealthy donors. Palmer, who has a wildly devoted following, used the crowd-funding website Kickstarter to raise $1.2 million to finance her last CD and tour. Mayday PAC already has some deep-pocketed patrons, including TED curator Chris Anderson, LinkedIn co-founder Reid Hoffman, and Brad Burnham, managing partner of Union Square Ventures, which has funded the likes of Twitter, Kickstarter, and Tumblr.Mark Shanahan can be reached at firstname.lastname@example.org.
