Look at his schedule for Thursday: No state business, he'll be leaving the state early in the morning on loan to the Romney campaign, ostensibly to campaign in Colorado Springs (same day as Obama!). He could easily divert and end up along side Romney in Iowa before anyone was the wiser.
Can we track his plane on flight aware? Like we did in 2008 with Palin? That was so fun. Gulfstream V, flight plan Scottsdale-->Anchorage-->Dayton Ohio, obvious what was going on many hours before the MSM figured it out. Freepers were all over it
I guess tomorrow at this time we will know.
