Upstaged by Sarah
Now we know why Obama didn't choose Hillary as a running mate. It had nothing to do with her baggage or husband, but rather a premonition of the development of the Sarah syndrome stealing the spotlight from McCain. It reminds me of JFK beginning joint appearances with his wife something like: "Pardon my intrusion; I know you're here to see Jackie." Of course, subliminally JFK knew she was a tremendous asset--certainly more so than having Johnson at his elbow. I rather doubt McCain would have chanced Palin had Obama chosen Clinton.
I hate to admit it but McCain shows confidence in himself despite his partner's dramatic space invasion. Obama on the other hand would have been wary with Hillary at his side.
