By the end of this day, four million of us might be registered to vote in November. Anybody who registers tomorrow will have waited too long. More from Bob Priddy. The deadline for registering to vote is the close of business today….Local election authorities say thousands of people have shown up to register in the last few days, many of them organized by voter-registration drives. People wanting to register can use a driver’s license or another form of identification including a student I-D or a utility bill with their current name and address on it to identify themselves. The co-director of elections for the state, Betsy Byers, says local authorities can do a quick but rudimentary check on whether the person is who they claim to be. She says they sound out verification cards and if the cards bounce back, the name is not put on the voter rolls. A statewide voter registration data base will help keep people from registering in two places. Byers says information entered into the system by a county clerk will be compared with information in other counties, and if there’s a match, the new county can pull the record from the old county…then notify the old county about the change. Missouri has about six-million people. By the end of this day, about two-thirds will be registered to vote. The Secretary of State is not ready yet to predict how many will actually cast a ballot, though.
