50 years ago the entrenched Byrd Machine, which controlled Virginia, did everything in its power to restrict the franchise.   Poll taxes, few registrars who were difficult to reach, blank applications to fill out (exactly, or you weren't registered), challenges at the polls -- all these National Democrats fought.   Obenshain and his Republicans are providing just a variant of the old attempts to squash the voters.   Disgusting, smarmy and un-American.   Keep up the pressure!
