In general, she said after speaking with officials in all 67 counties this morning, "all is going well." The spokeswoman noted that during early voting, 800,000 people cast ballots "and we expect much of the same today."

Three of the precincts affected by problems were in Broward County, which uses Election Systems & Software Inc. iVotronic voting devices, she explained.

"With approximately 5,000 machines deployed, there are always a few that do not start up properly," said Peter Corwin, assistant to the Broward County administrator. A percentage of these machine problems are usually caused by human error and can be corrected with a call to technical support, he said.

Corwin also said the call volume to technical support workers appeared lower than it had during the primary election.

Last week, during early voting, voters in both Broward and nearby Miami Dade County had complained of vote flipping -- that is, the candidate being chosen by a voter was not displayed on the voting screen. Officials assured the public no votes were lost.
