This morning’s Under the Dome highlights a Gallup Poll showing that John Edwards’ approval rating has fallen off a cliff.

The poll found a 21 percent favorable to 59 percent unfavorable ratio among Americans.

The story here is not that Edwards’ approval index has taken a nose dive in recent months. Instead, it’s a question: what illegal substance were 21 percent of respondents smoking that led them to approve of cheater-boy Edwards?

We’ll leave that one to the philosophers.
