McCain and Palin are a team chosen for different reasons. McCain brings experience - Palin brings values. If McCain croaks during the initial stages of his presidency then the response to Palin's lack of foreign policy experience is the republican's deep bench of tested foreign policy experts who can and will step forward to backstop a Palin led administration. Compare and contrast this to the cast of foreign policy nut cases that Obama brings in on day one.
To Tucker Bounds - it's all about the foreign policy team backing up Sarah Palin - not Sarah Palin's lack of foreign policy experience. And assuming McCain doesn't croak, Palin will get to understudy our best and brightest when it comes to dealing with foreign threats - experience that combined with her conservative values will turn her into a formidable force - most likely the republican franchise for the next 16 years which won't make Romney, Huckabee or a few other folks happy.
