In a rare campaign rally appearance, Barack Obama exhorted attendees to get out and vote. “One week, Wisconsin. One week,” he said. “One week from today you get to choose a new governor. And because early voting runs through this Friday, you don’t have to wait until Election Day. You can vote all week.” He then clarified, “I mean you can only vote once. This isn’t Chicago now.” After pausing for laughter, he added, “I’m teasing Chicago, I’m messing with you. That was a long time ago.” Yeah, well, Obama joked about having the IRS audit political opponents, too, and look how that turned out. Voter fraud benefits Democrats, which is why he’s laughing it up.
