I was skeptical of Jon Huntsman wanting to take on this responsibility, but if you consider it an express ticket to the front of the line for the 2016 nomination no matter how badly the ticket loses, it makes more sense.
If Sarah Palin had been a cannier, more disciplined politician she would have easily been the front runner despite the '08 loss.
Rick and John would be a very odd couple ticket. Among other things, John has a rather calm and realistic view of America's role in the world, and what it is prudent for it to do, and not do, and Rick wants to go to war with Iran ASAP as it were. Huntsman is also a free trader, and Ricks wants to get tough with anyone who takes away American manufacturing jobs, and as part of an "industrialization" policy, give special tax breaks to rust belt manufacturing. John is more of an IT guy, for whom it is time to just recognize that America's economy has changed forever, and Dorothy isn't in Kansas anymore, and in this case, won't ever be going home again, and that Chinese bashing is not going to accomplish anything positive, other than perhaps as therapy for America's bruised ego.
But it is a strange year, where predictions including mine are more often wrong than right.
