Romney or Pawlenty? — I think Pawlenty

Roll Call is reporting that the Secret Service has conducted a security sweep of the home of Romney’s sister.
Tim Pawlenty has cleared his schedule for today and tomorrow.
For what it may be worth (not much, considering last time), I think it is Pawlenty (one report says Romney is out). I used to think it was Romney, but with reports that Karl Rove was pushing hard for Romney, I’m guessing maverick McCain went the other way (you cannot push McCain around).
Update: John Fund’s detailed argument for Governor Tim Pawlenty as McCain’s vice presidential candidate.
Update #2: Jonathan Martin says Lieberman is out.
Update #3: RedState is calling it for Pawlenty, and they have a helpful bio on Pawlenty’s positions and accomplishments.
