The long lines are not unique to the Philadelphia region, a quick check of statewide news coverage shows.
From the Pittsburgh Post-Gazette:
"Steelers Coach Mike Tomlin arrived back in Pittsburgh at 3:30 after last night's Monday Night Football victory over Washington, went to the office, and about three hours later joined the queue. He passed the time by punching numbers into his cellphone, talking football with friends and thinking about how, with a day less than usual to prepare, he would ready his team for the Indianapolis Colts Sunday. Would he get to sleep sometime Tuesday? Probably not, he said. ``I can sleep,'' he said into the phone, ``when I'm dead.' ...'
At the Allegheny County bureau of elections, Director Mark Wolosik predicted a 75 percent turnout of the county's 956,000 registered voters. He was cautioning voters they could face lines if they try to vote from 7 to 9 a.m. or 5 to 8 p.m."
The Morning Call of Allentown, Pa. predicts 70 percent turnout in the bellwether Lehigh Valley:
"First in line at Wesley United was 48-year-old Paul Altpeter, a mechanical engineer with Air Products who had arrived at 6:20 a.m. when it was still dark outside.
It was also chilly outside, but it didn't matter. Altpeter hadn't slept well he was worried. A McCain supporter, he said he knew it was likely his candidate would taste defeat before the day's end, but he remained undeterred."
And the Patriot-News of Harrisburg finds a local Judge of Elections, who talked about the 'why.'
"We have a really strong early showing," said Judge of Election Joseph O'Connor. "People seemed very motivated to vote," he said.
At 7 a.m., the line was out the door. "My sense now it will be steady through the rest of the day," O'Connor said.
