"Will you still need me, when I'm sixty-four?"

538 says the she-Clinton probably doesn't have the back-up opp for 2012 the media seems to think. One of the reasons:

5. The Reader's Digest Problem. I have a friend -- a Clinton supporter, actually -- who joked to me that Barack Obama shouldn't worry about his current polling, because by the time November rolls around, half of John McCain's supporters will be dead. Gallows humor aside, Hillary Clinton has a little bit of this problem as well. And I do not think it is merely a matter of her supporters tending to be older than Barack Obama's. Obama's argument is at its core a generational argument, and Clinton is that the waning edge of that generation gap. I would imagine that a fair amount of her support comes from people who became wealthy during the Clinton era, or got married and started a family during the Clinton era, or migrated to this country during the Clinton era. As those experiences fade from memory, so will some of her support.
