Voting Machine Confusion Explained
Election officials say the problem started when the wrong counter was checked. The top counter keeps tracks of votes counted today. The bottom counter keeps tracks of votes cast in between service checks, and it already had some numbers when voting started Tuesday.
PHILADELPHIA-November 2, 2004 — Reports have circulated nationally that polling machines in Philadelphia had votes recorded on them before polling places opened. Officials say it was a matter of looking at the wrong numbers.
Political operatives are descending today on polling places around the state, looking for signs of voting irregularities.
Republican observers in Philadelphia are lodging some of the earliest complaints, claiming that voting machines in the city already had thousands of votes recorded when the polls opened.
City election officials say the GOP poll watchers got it wrong.
Deputy City Commissioner Ed Schulgen says the observers pulled the numbers from an odometer that records every vote ever cast on the machine in every election – not the number to be counted today.
In rural Mercer County, Commissioner Olivia Lazorsome says some voters are apparently having problems with new electronic voting machines, causing longer-than-usual delays.
