So, John McCain's running mate will be Alaska Governor Sarah Palin. Despite her right-wing politics, the 44-year old mother may prove attractive to those waverers who were disappointed by Hillary's loss, and remain unconvinced by Obama.

One can only hope that Obama has some people of similar tactical skill on his team. Having done the business in Denver, Obama needs to ensure he gives as good as he gets.
