Original Maverick
John McCain has won over many voters with his self-styled reputation as a "maverick." And his running mate, Sarah Palin, often refers to the Republican ticket as a "team of mavericks." But tonight, John Donvan traces the origin of the word to 82-year-old Terralita Maverick in Texas. She happens to be an Obama supporter, as she told "Nightline" in our "50 States in 50 Days" tour.
