The Vice President of the United States is an attack dog in campaign season, a tie-breaker in the Senate and, ultimately, the back-up Decider. McCain chose Sarah Palin, the folksy, first-term governor of Alaska. Obama chose Joe Biden, a 35-year veteran of the Senate with a reputation for speaking his mind (for better or worse). They're a heartbeat away from the presidency. Who's ready? An original GOOD Video.
