In too-close-to-call Virginia, voters are being deluged with print, radio and TV ads from the presidential campaigns as well as urgent pleas from former Govs. George Allen and Tim Kaine, who are both running for the commonwealth’s open U.S. Senate seat. In the ensuing din, little attention is being paid to a proposed constitutional amendment to protect citizens from the abuse of eminent domain by local governments, utilities, and housing and transportation authorities, among others.
