Fairly Smooth, Considering

Machines malfunctioned, tempers flared and edgy voters often waited hours Tuesday to pick a president in a contentious race watched by thousands of monitors who expected the worst.

But by the close of East Coast and Midwest polls, only scattered local snafus had been reported in an election turnout that was shaping up to be the heaviest in years.

"So far, it's no big, but lots of littles," said Doug Chapin, director of the Election Reform Information Project, a nonpartisan research group. "We know of no major meltdowns anywhere along the lines some people were worried about."

Despite all the lawyers, election-rights activists and partisan voting monitors who descended on polls across the country intent on uncovering voter fraud, the biggest complaint appeared to be long lines that forced voters to wait hours, in queues that circled buildings and wound down streets.

The extremely high turnout, and massive voter-registration efforts by Democrats and Republicans, were considered the cause.

About 50 percent of all voters said they were very certain ballots in their state would be accurately counted, according to a national Associated Press exit poll conducted by Edison Media Research and Mitofsky International.

Still, Common Cause reported more than 175,000 calls to its national voting hot line. The citizens' lobby group said extremely high voter turnout caused complaints of ballot shortages and overwhelmed polling officials.

Hyper-vigilance appeared to be the order of the day, which in some states prompted poll closures and unfounded complaints.

In New Jersey, for example, a suspicious substance later determined to be spilled salt prompted the two-hour closure of a Mount Laurel precinct. In Pennsylvania, zealous GOP election monitors complained that some Philadelphia voting machines already had thousands of recorded votes when the polls opened at 7 a.m.

Local election officials quickly explained that voting machines registered every vote ever cast on them — like mileage on a car odometer — and that did not constitute evidence of fraud.

"It's absolutely ridiculous," said Deputy City Commissioner Ed Schulgen.

A Democratic source tells CBS News Republicans filed a federal lawsuit in the eastern district of Pennsylvania asking for more time to count absentee ballots from Philadelphia because they have not had sufficient time to validate the absentee voters.

Pensylvania Republicans tell CBS News the Philadelphia Board of Elections has be ordered to provide a list of those who have requested absentee ballots. The case will be argued Wednesday morning. The Republicans say the ballots may not be opened or canvassed in the meantime.

Democrats there say there are 13,000 ballots at issue -- and in closely contested state, with slim margin of victory -- they could make the difference in declaring a winner.

In Colorado, Republican Party officials said a lawyer for the Democrats showed up at an Eagle County precinct with a list of registered GOP voters, planning to challenge them all. Democrats acknowledged it was true.

In other closely contested states — including Iowa and Michigan — the liberal group MoveOn.org was accused of disrupting local precincts.

In Ohio, a woman filed a lawsuit on behalf of voters who didn't receive absentee ballots on time, asking they be allowed to cast provisional ballots. Later, a Toledo federal judge granted her request.

Republicans in Ohio won dual victories from the U.S. Supreme Court, which refused to reverse two federal appeals court rulings granting GOP poll watchers the right to challenge voters.

Also in Michigan, the NAACP filed a Justice Department complaint, saying it received 35 complaints that GOP poll watchers were harassing voters in Detroit.

CBS News Legal Analyst Jonathan Turley notes that many legal actions taken Tuesday were "designed to preserve issues in anticipation of litigation if the election is close. …When one looks at the entire picture, there is collectively much more litigation (being) reported. The campaigns have been very skillful in slowly filing these actions to avoid the appearance of lawyering the election.

"There is a significant and comprehensive range of litigation. Some of it is meritless but some of these issues have bite."

In Wisconsin, Republicans said vandals spray-painted "Illegitimate Democracy" across state party headquarters. In Milwaukee, police said tires were slashed on about 20 get-out-the-vote vehicles leased by the GOP.

A Democratic official in Cleveland claimed he was thrown out of a church basement by a screaming poll judge. Another judge allowed him to return.

In Florida, two Bush supporters filed a lawsuit seeking at least $15,000 in damages, claiming they were punched, pushed, shoved and spat on when they showed up at a Halloween rally for Democratic candidate John Kerry, dressed as giant flip-flops.

New touch-screen voting machines, criticized by computer scientists and several elections officials as susceptible to hacking and malfunction, were used Tuesday in 29 states and the District of Columbia. Only Nevada has mandated the machines produce paper receipts, which could make recounts more reliable.

In Florida, which gave the 2000 election to George W. Bush on the basis of 537 votes, 10 touch-screen voting machines failed at various precincts in Broward County. Nearly half the state's voters were using the ATM-like machines.

Provisional ballots, new this election, also prompted disaster fears because they could delay any recount efforts. Any voter whose name does not appear on precinct rolls is entitled to cast a provisional — or paper — ballot. But elections officials must individually certify them as being cast by registered voters before they can be counted.

Some polling stations in the important swing state of Pennsylvania saw provisional ballots run out. Precincts scattered across the state stayed open past the scheduled closing time of 8 p.m. because of huge lines.

Provisional ballots also ran out in New Mexico, and were quickly replaced by election officials.

In New Orleans, problems with electronic machines, some of which did not boot up, forced precinct workers to tell voters they would have to come back, said voting activists.

"New Orleans wins the award for the worst voting situation in the country when it comes from electronic voting machines," said Cindy Cohn, legal director of the Electronic Frontier Foundation.

The complicated issue of counting absentee ballots also added to the confusing array of new machi
