Officers say someone broke into the building on West Mineral King near Central. They believe it happened sometime after 9 p.m. Saturday night.
The thieves smashed a glass door to get in and stole a big screen T.V., a computer, and ransacked the office. Members of the Democratic Party had initially canceled a viewing party planned for Monday's presidential debate. They have since said the viewing party will go on as originally planned.
Anyone with information about the burglary is asked to call the Visalia Police Department.
