True, but my overall way of looking at it is 'the older the wiser'. If we're going to have to strategically disengage wartime actions in the middle east while also having a full understanding of the policies of the participant, who better than an elder leader with actual military experience and military leadership skills? A person who can hear all sides and draw a conclusion of off both advise, and personal experience.There are parallels, though, that bear consideration. The Republican party was emerging in power, and Lincoln was handed a terrible mess left behind by Buchanan, whose policies had laid the foundation for the secession of the South. Lincoln made some mistakes, including relying too heavily on ineffectual generals like McClellan, who dithered away precious time while the South built their military strength. The next president will have his hands full trying to disengage peacefully from Iraq, while trying to take down Al Qaeda and the de-fang the Taliban.
As for experience - no single person can do all the jobs of the administration - the trick is to get (and heed) good advice from people with in-depth knowledge of the problems and opportunities at hand, and delegate responsibility wisely, and demand accountability and follow-up.
