The way I see it, Boucher wins the more liberal I-81 Roanoke to Bristol corridor (which includes Virginia Tech, Hollins University, Emory & Henry College, etc, and the larger towns like Blacksburg, Wytheville, Marion, Abingdon, and Lebanon), but Griffith takes coal country (Buchanan, Dickenson, Russell, Tazewell, and Wise counties--not sure about Scott and Lee counties).
It's going to be close, but Griffith has the momentum now and may very well pull this out.
