But here’s what came through clearly. A statewide recall -- never popular on either side – was the reluctance hardest to overcome for Barrett, who didn’t even enter the contest (he had a mayoral race to win first) until the voters had decided they would oppose the recall he was leading. The exit polls suggest they had decided before he could possibly have mounted evidence about Walker’s policies, job numbers and other much publicized claims. The main thing the money game accomplished was to prevent any contrary messaging to charge through, knock decided heads together and change minds.
