Staff Writer Less than a week before election day, watchdog groups are expressing concern about how the structure of voter registration may open the door for electoral manipulation. Linda Paine, co-founder of the Election Integrity Project, a statewide watchdog organization, said California is the only state in the U.S. not to maintain a consolidated statewide database of voter information. In fact, the California Secretary of State has been working since 2005 to implement VoteCal to bring the state into compliance with the federal Help America Vote Act of 2002, which mandates states maintain a single, uniform statewide voter registration list, according to the Secretary of State website.
