I was a little skeptical last week when Wisconsin Democrats released the first batch of signatures for their recall campaign against Governor Scott Walker. They'd gathered over 100,000 signatures in four days, an impressive haul no doubt, but the first batch of supporters were always going to be the easiest to bring around. State election law requires that the signatures exceed 25 percent of the ballots cast in the relevant election, totaling over 540,000 in Walker's case.
