Rhode Island has more registered voters than would be expected based on census numbers.
Rhode Island should have 592,672 voters based on U.S. Census Bureau estimates of the number of adults and the percentage registered to vote in the 2008 presidential election.
But 781,770 people are registered, an excess of about 32 percent.
The percentage of excess voters is the highest in New England.
Excess voters can wind up on the rolls when voters die or move without elections officials noticing.
Secretary of State Nellie Gorbea is trying to clean up the voter list.
Rhode Island is working with other states to detect people who move. It has begun online voter registration, which makes it easy for voters to change their addresses.
