It looks like there was a shred of truth to the strange post by Not Larry Sabato some time back about Greg Werkheiser standing on David Englin's front lawn. On Saturday, Raising Kaine posted this call for action. It looks like the forces are marshaling themselves for the July 4th parade in Lorton, the heart of the 42nd district.
This is the House of Delegates battleground, folks. If Tom Davis really is going to be there in person, it is a good guess he is foresaking his traditional and time-honored place in the City of Fairfax 4th of July Parade, which begins an hour before the Lorton parade. For those unfamiliar with Northern Virginia topography and trafficology, it is theoretically possible for Davis to do both parades personally. It is also theoretically possible for NASA to land on Mars that same day.
This is the race to watch. If Werkheiser has managed to draw out Davis, Albo's internal poll numbers must be sagging. You can tell a lot about who needs propping up by where the big dogs show up on a major holiday. This could also signal that John Mason has a cakewalk on his hands.
I'll post an update to this tidbit once I've got reports from the 4th of July events. Scheduling for candidates is always a fluid game, so we're going to see whether the post on Raising Kaine is accurate, or whether it is primarily designed to draw out volunteers.
