Sporadic problems are being reported today at polling places around the country.

One voting machine in Pennsylvania lit up for Mitt Romney when a voter pressed the button for President Barack Obama.

The machine was recalibrated.

In Philadelphia, dozens of Republican inspectors were blocked from polling places, prompting party officials to obtain a court order providing them access in the heavily Democratic city.

Ohio also saw a court battle -- this one involving a lawsuit claiming the state-installed voting software could allow people unconnected to official election boards to manipulate ballots.

A judge dismissed a lawsuit seeking to stop the software's use.

In Florida, a robocall glitch recycled calls intended for yesterday -- telling voters they had until ``7 p.m. tomorrow'' to vote.
