"Allegedly" is right. The level of rhetoric here is nuts: Mayday's stated goal is to change the way that campaigns are funded such that each person (voter) can contribute equally to the campaigns of their choice.
That's the exact problem I have with it. It's an effective tax raise, and what happens to the money raised? It goes to support candidates I might vehemently disagree with. To buy them TV commercials. I find that pretty objectionable.
I have no issue with Lessig's end-goal here, I think it's noble and needed. But the way he's going about it is awful, and I won't be contributing money to it.
