The question begs to be asked

Listing a host of issues on which he said McCain has the same position as President Bush, Obama said, "That's not change."

"That's just calling something that's the same thing something different," Obama continued. "You can put lipstick on a pig. It's still a pig. You can wrap an old fish in a piece of paper and call it change. It's still going to stink, after eight years.


"We've had enough of the same old thing."

The question is, if Obama was referring to Palin as the pig, who was he referring to when he talked about the stinky old fish?
