Individuals may register to vote at County Voter Registration offices, through the mail, at a Department of Transportation office, or at various other government agency offices.[2]
Voters must register 30 days prior to the election in order to be eligible to vote; for the 2008 Democratic primary, this means that March 24 is the last day to register.[2]
