Polls have opened for Election Day in the swing state of Colorado for the final day for voting for the presidential race and several statewide and local races.
Polls show the presidential race is a toss up, though President Barack Obama has a slight edge over challenger Mitt Romney in the latest Denver Post poll.
Due to early voting and mail ballots, many Coloradans already have cast their vote. The secretary of state's figures show that 675,797 Republicans, 642,834 Democrats and 534,012 unaffiliated voters had turned in ballots.

Voters will also decide whether to legalize recreational use and retail sales of marijuana, three competitive congressional races and control of the state legislature.
Additionally, several cities and school districts, including Denver, are asking voters to approve bonding and tax measures.
With lines forming at polling stations early, at least one in Jefferson County — the one swing county said to be the most likely to decide Colorado's direction in this election — was off to a rocky start .
Several people were turned away at Columbine Library, 7706 W. Bowles Ave., in Littleton after poll workers were unable to find the voter's names on the registration list. Jim Mitchell of Littleton said he's been voting at the site for years and never had a problem until now.
"Apparently they have the wrong registration book," said Mitchell. "We have to go to a different place."
Chuck Welle of Lakewood left the site before he was able to vote because the lines were getting long. He said he wasn't necessarily frustrated and would come back at lunch time.
"I gotta vote," said Welle. "It's my right."
Littleton resident David Ahl waited about 15 minutes before poll workers finally found his name in the registration book.
"It was pretty testy in there for a second," Ahl said. "People were very impatient. But they finally figured it out."
Josh Parsons of Morrison was turned away after he was told he was in the wrong precinct. He said he was frustrated, "to say the very least."
"I'm not even sure where I'm supposed to go now," said Parsons.
By about 8 a.m., poll workers at the site said they had the situation under control. They said they had the right registration book all along, but that the voters' names were organized in a way that was confusing.
In Arapahoe County, another contentious county for Colorado, five voting machines were down at Mrachek Middle School in Aurora and only one poll worker was on duty for the provisional ballot line, causing a wait times of two hours at the beginning of the day.
Wanda Ramey, a volunteer with the League of Women Voters who was there handing out surveys to voters, said nine voters had left without voting this morning because of the long lines.
"It was torture but it was alright," said voter Lisa Vasquez of Aurora. "There's only one person moving like molasses and you couldn't fill it (the provisional ballot) out in line."
Matt Crane, a deputy of elections, said the downed machines were not a problem because there was no wait for machines and that more resources were going to the provisional ballot line, though it was still long.
Arapahoe voters were seeing long lines at Faith Presbyterian Church, 11373 E. Alameda Ave., in Aurora, but not so many hiccups.
The lines were about 30-40 people deep just after the polls opened.
"We gotta get back in the swing of things," said lead machine judge Virginia Fuehrer.
Poll watcher Michael Alper said poll workers didn't run the paper tape record on a few of the machines when they logged them in, but the machines showed zero votes recorded before people voted, so he wasn't worried.
Michael Townsend, of Aurora, who prefers voting on Election Day, said his voting experience went a bit smoother this year than in previous years past.
"There's chaos to every Election Day, but this was pretty straightforward." Townsend said.
Lavelle Burnham of Aurora said her experience with the machines was "quick and efficient" as she was trying to get in as early as possible for work.
She added: "I think if you don't vote, you don't have a right."
