Lawrence Lessig, a Harvard law school professor who has long opposed “big money” in politics, wants to start a super PAC “to end all super PACs.”

“Embrace the irony,” he says of the fact that he needs one in order to kill them.

Mr. Lessig wants to first raise $1 million in 30 days and then an additional $5 million. He said it would be “built first from small-dollar contributions.” If either goal is met, Mr. Lessig says that he will ensure that the amounts will be matched, presumedly from rich donors.

If May One, as he is calling it, did reach its first two fund-raising goals, it would have $12 million to spend, enough to make a mark in five House races. He won’t say which ones, because why give other super PACs a heads-up? They would certainly not stand by.

Mr. Lessig believes that this year’s elections will be a proving ground for his PAC. His ultimate goal is raising enough money to elect a House majority and 60 senators who will vote for “fundamental reform” of the campaign finance system.
