Before I left DC back in December 2006, this rumor of Cropp people selling her out was floating around but no names were ever associated with the sell out.
Admittedly, Cropps visible presence in ward 3 by means of yard signs, posters, literature and other matters were minimal compared to other wards but I do recall that Rees was putting up Cropp signs along Wisconsin for Cropp he got from Jacobsen.
