Unsubstantiated, Unsupported Thoughts on Moran-McAuliffe-Deeds

If the rumors that Terry McAuliffe is considering a run for Governor in 2009 are true, his presence in a primary with Brian Moran and Creigh Deeds has to work in Creigh's favor does it not? 

The appeal, as far as I can see it, of a McAuliffe candidacy is his long service to the party as a straight-talking, "northern," progressive, business Democrat.  His voters will live in Arlington, Alexandria and Fairfax, and unless I'm missing something, connecting with downstate Democrats will be a more significant task. 

In this model, Moran and T-Mac will be left to compete over the same voters while Deeds does well downstate and finds enough moderate Democrats in the Golden Crescent to put him over the top.

I'm sure there are things that I'm not considering, but that's why there's a comment section.
