Pennsylvania was also the state that saw the first court battle over voting issues today, as Pennsylvania GOP officials protested to the Philadelphia Court of Common Pleas that about 75 Republican inspectors in Philadelphia were not able to access polling places.
"This was a shameless attempt from the Obama campaign to suppress our legally appointed Republican poll watchers in Philadelphia and they got caught," Rob Gleason, chairman of the Pennsylvania Republican Party, said in a statement.
Democrats argued that the issue was about credentialing, and that they were trying to ensure that the inspectors had valid certificates in order to be seated at the polling places. The court quickly issued an order saying that certified inspectors should be allowed into their designated polling places.
Republicans also went to court in Pennsylvania to have a judge order a polling place in Philadelphia to cover a mural of Obama painted on the wall of a Philadelphia elementary school.
The court battles are emblematic of both campaigns' reliance on attorneys and poll watchers across the country to monitor voting, especially in swing states. Clawing their way to victory will mean the campaigns of Mitt Romney and President Obama must ensure that problems with access or machines don't impair their candidate's ability to win the election.
In large part, Democrats fear voter suppression tactics, while Republicans are wary of voter fraud.
Volunteer attorneys affiliated with both sides are on the ground at polling stations in swing states, wired into campaign headquarters with smart phones and apps, ready to present challenges to local judges.
Both sides will be concentrating on issues such as voter registration and eligibility, poll watcher activity, ballot counting, polling hours and machine malfunctions.
In many swing states, however, including Ohio, Colorado, Nevada, Iowa, and Wisconsin, election officials tell ABC News that voting is running smoothly and going as expected.
If states begin to see hiccups in their smooth operations, including malfunctions or legal challenges, judges in all fifty states are on stand-by today to issue quick rulings and help iron out contentious issues.
