Ben Smith at the Politico has the stunning revelation:

A voter at Sen. Barack Obama's town hall meeting in Greensburg, Pa., yesterday asked whether he would consider eliminating the penny.

"We have been trying to eliminate the penny for quite some time -- it always comes back," Obama said. "I need to find out who is lobbying to keep the penny."

Somebody in the crowd pointed the finger at Illinois, the home of Abraham Lincoln.

I'm impressed that Barack Obama has the courage to take on the beloved penny but shocked that he's going against his homestate's interest in the penny.
