Jennifer Lin reports:

Voter Action, a national voter rights group, has asked a Philadelphia judge to extend voting hours tonight until 10 p.m., and to use paper ballots at all voting places where broken machines have been reported. The city's Board of Elections seems certain to object. The hearing is expected to begin momentarily.

John Bonifaz, Voter Action's legal director, says his organization has received about 150 complaints from Philadelphians today, a rate he says is roughly double what they've seen in primarires elsewhere. Interestingly, the leading local election watchdog, the Committee of 70, has said problems at the polls today have been relatively routine. We'll have more shortly.
