With the music still off, we squeezed in another question about former Massachusetts governor Mitt Romney’s comments on Wednesday night’s “Tonight Show with Jay Leno.” On the program, Romney seemed to take a jab at Palin’s decision to step down as Alaska’s governor. “It’s hard to imagine a circumstance where I would quit,” Romney said.

As of today’s book signing, Palin indicated she hadn’t heard Romney’s remarks. “What did Governor Romney say on the ‘Tonight Show’?” she asked us.

Upon hearing his comment, her response was brief. “Oh, he probably had some different conditions,” she said. It was an apparent reference to the controversies that swirled around her final days as Governor including ethics complaints and a legal dispute over a state trooper who was once married to her sister. Palin’s actions were cleared by a state board investigating the matter. In her resignation speech last year, Palin suggested that costly legal battles had forced her to step down.
