AP has a round-up of some early election activity:
"About a third of voters were using new equipment, and problems in several states were reported right out of the gate. The government deployed a record number of poll watchers to the many competitive races across the country.
"Glitches delayed balloting in dozens of Indiana and Ohio precincts, and Illinois officials were swamped with calls from voters complaining that poll workers did not know how to operate new electronic equipment.
"In Delaware County, Indiana, officials planned to seek a court order to extend voting after an apparent computer error prevented voters from casting ballots in 75 precincts.
"Florida officials, working to avoid a repeat of the vote-counting debacle of 2000, fielded extra voting machines, paper ballots and poll workers.
"In the Jacksonville suburb of Orange Park, Florida, voters were forced to use paper ballots after an electronic machine broke."
