OLYMPIA, Wash. (AP) - Secretary of State Sam Reed says there have been 180 changes in state election law and 1,100 administrative rule changes since the disputed governor's race four years ago.

The biggest change may have been the creation of a statewide voter database two years ago that consolidated all 39 county systems into one.

Since then, more than 450,000 voter registrations have been canceled. Those include duplicates, people who have moved out of state, ineligible felons, and the dead.

Reed says voters can have confidence in the integrity of the system.

King County, which has about a third of the votes in the state, also says it has improved its system. Four election locations have been consolidated into one office in Renton.

A spokeswoman, Bobbie Egan, says procedures are in place to prevent the mistakes of '04 from happening again.
