Ben Smith of Politico broke this story, but Josh Marshall's team at Talking Points Memo is doing the most follow-up. (By the way, Josh should get the Pulitzer next year for his coverage of the Bush administration's abuse of power in firing U.S. attorneys for political reasons.)
Anyway, click the link. It turns out the NYPD didn't just drive Rudy to visit his girlfriend, and didn't just drive Rudy's girlfriend when he wasn't around, they also sometimes drove her friends and family in a city-owned car.
Also, New York City cops sometimes walked her dog.
No way can Rudy's campaign last another month.
