Some good advice for Republicans:
Expel your base or retreat into an echo chamber: If those choices seem dispiriting, Republicans can take heart. They're the same false alternatives that the Democrats allegedly faced four years ago. Then a politician who hadn't fallen behind the bipartisan Iraq war -- but, unlike Howard Dean, actually wanted to be president -- came out of nowhere to beat his party's establishment and take the White House.
There's a lesson there. If I were a Republican, I'd ignore the inane Palin debate and start looking around for a politician who had the good sense to break with the bipartisan consensus and oppose the bailout bill before it passed. Then I'd start planning an insurgency.
Mike Pence in 2012! Your insurgency awaits.
