Interesting choice and I believe a mixed bag. More than anything else, I think this is a move to placate the base of the party. The base believes Romney is a closet moderate, and evangelicals weren't thrilled about the whole Mor(m)on thing. So fundamentally, this is a move that will generate more excitement at the convention and for the campaign in general among the base. Anyone tempted to stay home in November will be less tempted now.
OTOH, the whole idea of privatizing Medicare and issuing vouchers for insurance is a scary proposition. Don't get me wrong. I think we need to have a frank discussion about Social Security and Medicare in this country. Social Security, Medicare and Medicaid are about 63% of our budget. (Add in military and debt payments, and you have 80% of our federal budget.) And I keep hearing that Medicare as it currently exists will no longer be feasible in another decade or so, and the same for Social Security a decade or so after that. Social Security is easier - you can keep kicking the can down the road by moving the eligible age back. Medicare and Medicaid are much harder because medical costs are out of control. But I don't think our politicians or populace are mature enough to face that discussion in a rational manner at this time. And color me cynical, but I'm suspicious that many a senior will not be able to afford the cost of insurance if they have to purchase it on their own. And color me even more cynical, but I'm guessing that if you live in Florida you might just be viewing an ad or 2 targeted at seniors about their Medicare being cut off.
So while this move will certainly energize the base, I'm guessing this is exactly who the Obama administration wanted to run against. Not that they were afraid of Rubio, TPaw, Jindal or Portman. But now the message is even more clear - we may not be doing great, but Romney and Ryan are downright scary. The 1st rule in picking a veep is do no harm. And while I know Romney felt like he had to mollify the base, I think he may have violated rule #1.
