In today's mail was a piece from Loudoun County Board of Supervisors Chairman Scott York that listed the endorsement of all the local Republican Loudoun County candidates except one - Suzanne Volpe. The same is true of his website. Volpe's website, moreover, has no reference to a York endorsement (or any endorsement for that matter other than Frank Wolf). Steve Stockman, the other Republican candidate for chairman, has no endorsements listed on his site.
Given that even Mick Staton has endorsed York, it makes one wonder whether this is just a timing issue or if it's something deeper. It certainly could be timing - Dick Black's reciprocal endorsement of York, for example, must still be in the mail.
