Former vice presidential candidate Sarah Palin announced today that "she is resigning from office at the end of the month, raising speculation that she would focus on a run for the White House in the 2012 race," according to AP.

If you recall, Gov. Palin ran with Sen. John McCain during the 2008 election. She is most famous for having an underage daughter who was with-child, a signature updo hairstyle, and providing Tina Fey with choice material.
