Figuring out who John McCain is going to select as a vice president this early in the game is very difficult — not just because Johnny Mac really is a maverick who could make an unpredictable choice, but because there are so many different directions he can go. Will he choose a vice president who can help him patch things up with conservatives or will he go the other way and choose someone who would broaden his appeal to independents? Will McCain pick a veep who will add strength to the ticket as a whole or will he narrow his focus and take someone who can help in a particular state or demographic group?
