The campaigning is wrapping up, the voting is under way and the problems are mounting.

In Lebanon County, Pa., the polls will stay open later than scheduled Tuesday to make up for votes lost because of the glitches.

According to the group Common Cause, an election watchdog monitoring votes across the country, as of Tuesday afternoon, more complaints of problems at the polls continue to come in from more voters in Pennsylvania than any other state.

Here and across the country, most of the confusion at the polls is related to the new electronic voting machines, but in Pennsylvania, the problems appear to be widespread.

Of the top 10 counties across the nation from which voter complaints are reported to Common Cause, five are in Pennsylvania. Lancaster County is fourth overall in the country and Montgomery County is fifth.

Allegheny, York, and Philadelphia counties rank eighth, ninth and tenth, respectively.

Call 4 Action reporter Aaron Saykin asked, "Why are there so many problems concentrated for some reason in the Pennsylvania and Pittsburgh area?"

"Good question," said Barry Kaufmann of Common Cause. We thought we had a lot of these questions, a lot of these problems solved. The Department of State was doing extensive training. I'm not sure what the answer to that question is yet."

Many of the reports WTAE Channel 4 has received locally involve the electronic voting machines not working properly or not being operated properly.

The new machines were supposed to make things easier.

Congress ordered all states to move toward electronic voting after the recount fiasco in Florida during the 2000 presidential election. For many states, this year is the first year it was used.

According to Common Cause, there also have been complaints from voters about their names not being found on registration lists or that they're being forced to show photo identification in cases where it's not required.

"Do you think there may be a basis for legal challenges to the point where we might not know who the winners are for weeks?" Saykin asked.

"Easily," said Chellie Pingree of Common Cause. "I think that's a huge concern with so many contested elections and that the balance of the House and the Senate may be in question here."

If you're having a problem at the polls, there are two numbers for you to call. The first is for Common Cause: 1-866-MY-VOTE-1. The other is for the Pennsylvania Department of State: 1-877-VOTES-PA.
