OK, I don’t have before me the list of so-called superdelegates, nor do I know which have aligned with Obama or Clinton (or anyone else, for that matter) to date. However, that last point would seem moot anyway, since superdels can shift allegiance with impunity. In fact, under normal circumstances (which we're clearly not in) they're expected to abandon any earlier commitments once the putative nominee emerges. That being said, here’s the thing I don’t get about the Clinton campaign’s reported strategy of wooing a big honkin' majority of superdels, as a way of trumping Obama’s now-all-but-certain advantage in pledged delegates going to Denver: As I understand it, the vast majority of superdels are either currently elected or (let’s face it) aspiring officeholders. As such, when it comes time to choose, each of them will have to answer a fairly simple question: Which of these two, at the top of our ticket, will attract more people to the polls to cast their votes for me in November? Remember, this is not a question that most of them have ever had to answer. For years they've simply fallen in line, signed on with whoever they were given by the rank and file, and hoped for the best. But this time, they can, in a very real way, influence their own electoral fate. Now, I suppose one could argue that in the bluest of blue districts, the answer to that politically selfish question could well be “her.” But in all those red or purple districts, would anyone with a whit of political acumen really fail to see that Obama will be better able to draw newcomers, Independents, and even a few R's over to down-ticket Dems? Seems to me that any “red” or “purple” superdel dumb enough to opt for a Democratic presidential nominee who will give dispirited newcomers a reason to stay home, and drive Independents to McCain, will get what s/he deserves. And I like to think there aren't that many dumb superdels.
