A little logic...
If it's six of one and half dozen of the other, how come any time someone comes up with something (either real or imagined) that looks like it might somehow prevent incompetents, felons, illegal immigrants, the uneducated, and outright mouth breathers from voting, it's only the Democratic Party that stands up and shrieks that their votes are being stolen?
If what you say is true, why don't the Republicans object equally? If their voter base contains these gasbrains, why aren't they fighting for the gasbrain vote as hard as the Democrats do?
