The M word

Maverick
From Wikipedia, the free encyclopedia

A maverick is an unbranded range animal, especially a motherless calf; it can also mean a person who thinks independently; a lone dissenter; a non-conformist or rebel. The word first arose in mid-19th century America from Samuel Augustus Maverick, a Texas politician with a large ranch full of unbranded cattle.[1]

Number of times Palin described McCain as a Maverick - 16, during the Palin/Biden debate.
