I had thought the same thing yesterday. Palin can speak about the American values she has. Obama and Biden can only trash them. 
Palin lives the American dream. Obama and Bides see it as a nightmare that they must wake us out of.
Palin's infectious energy and verve are a severe counterpoint to the pain and anguish portrayed by Obama and Biden. Even McCain was truly energized by her.
Palin has the potential to be the next Reagan or Thatcher, provided McCain brings her along as VP during his administration, giving her solid responsibilities and duties so that she will be ready at whatever point McCain is done
