"That's only six years." -- Rep. Grace Napolitano, D-Calif. shows her math skills in response to the realization that she's breaking her campaign promise to limit herself to three terms.

She admits that her support for term limits was a factor in her first election to Congress in 1998, when she signed a pledge saying, "I, Grace Napolitano, declare and pledge to the citizens of California: I will not serve in the United States House of Representatives for more than three two-year terms."

As with most campaign promises, it might as well have been written on toilet paper.
