At the Alexandria Democratic Committee meeting last night, the Chairman of the Virginia Democratic Party, Kerry Donley, warned of a potential problem with primary voting. Because the Democratic primary is being held on the same day as the Republican primary, the State Board of Elections wants to put both primaries on a single ballot. While a voter is only allowed to vote in one primary or the other, if there is only one ballot, there is no way to ensure that they don't vote in both primaries.
This is a serious problem—imagine if large numbers of Republicans decided to vote for the weakest Democratic candidate in a House of Delegate's primary, with the hopes of giving the advantage to their Republican opponent.
Call your local registrar right away and request that they produce separate ballots for the Republican and Democratic primaries, and that they have two separate voting machines at every polling location.You can find their contact information here.
