Why do Republicans work to depress voter turnout?

Good God, yet another story of the Secretary of State trying to confuse people into not voting. Signs at deputy registrar offices say "It is too late to register for the November 2, 2004, General Election," but neglect to say that people can still register at the polling place on election day. The director of Driver and Vehicle Services, Pat McCormack, said that this information came from the Secretary of State's office.

How hard would be it to have a sign that said, "It is too late to pre-register on your driver's license application, but you can still register at the polls on election day. Mary Kiffmeyer is a disgrace to the office of Secretary of State. Instead of working to get as many people as possible to vote, she has consistently taken steps to deny people the franchise. This seems to be the m.o. of Republicans across the country. How do these people sleep at night?
