Maverick: being independent in thought or action or exhibiting such independence. John McCain has spent months referring to himself as the maverick. A statement that causes even the family of Samuel Augustus Maverick, where the maverick term was originally coined, to cringe. You can't be a maverick when you agree with Bush and the Republican practices for 26 years. Obama is the true maverick with new ideas and fresh perspectives on why we need change in America today. Think before you vote! Vote Obama and Biden in 2008.
