Using methodologies based on VPAP as explained in the discussion of Jim Clem's campaign money, it is useful to look at the 27th Senate District and the 33rd House of Delegates District races.
In the 33rd House of Delegates district, Joe May has received 16% of his campaign contributions from within Loudoun County and Clarke County. Marty Martinez has received 43% of his contributions from within Loudoun County and Clarke County. Apparently, the largest industry contributor to Joe May's campaign is Transportation, including "Private Highway Companies." It's interesting that the Greenway ends just shy of Joe May's district.
The 27th Senate District includes all or part of four localities: Loudoun County, Fauquier County, Clarke County, Frederick County and Winchester City. Jill Holtzman-Vogel has received 42% of her campaign money from within those localities. (none of it from Clarke County, interestingly enough). Karen Schultz has received 59% of her money from within those localities.
