Because it’s never too early:
Mark my words, the 2012 primaries will come down to Jeb Bush vs. Please God Not Jeb Bush, and Palin is the obvious PGNJB candidate. If the field gets overcrowded with a bunch of wannabes — Huckabee, Romney, etc. — dividing up the PGNJB vote, then we’ll get Jeb Bush.
OK, maybe it’s slightly too early.
