A special Arizona House Elections Committee hearing is set to examine problems that led to long lines at last week's presidential primary election.
The panel has asked Maricopa County Recorder Helen Purcell to testify Monday about the hours-long lines at polling places in the state's largest county.
Purcell cut the number of voting locations from 200 for 2012's presidential primary to 60 at last Tuesday's election. She has taken the blame for miscalculating voter interest.
Secretary of State Michele Reagan plans to announce results of a preliminary review before the hearing starts. The review will examine polling place cuts and the role of the state's voter registration system, which may have changed some party registrations to independent during routine address changes.
Independents couldn't vote in the primary.
