McCaskill and "Idiots"

At first glance of the article's title, one could be forgiven for thinking Senator McCaskill was referring to her voters when she said, "These people are idiots."

Nope. She didn't mean them.

The "idiots" to whom she was referring are people who are laughing all the way to the bank, as they say.

So, who's the real idiot, Senator McCaskill?
