Most voters aren't waiting until Tuesday to cast ballots. They are opting for mail-in or early voting.
President Barack Obama and his Republican rival Mitt Romney will both rally supporters in Colorado this weekend to try to convince those who have yet to cast ballots.
Trouble is: most of those people already have their minds made up.
"Some people do wait until they get to the polling place to make up their minds," 9NEWS political analyst Floyd Ciruli said. "But those are probably fewer than ten percent of the people left."
It's a tiny slice of the electorate, but it could be enough to swing Colorado and its crucial 9 electoral votes.
Friday's count of the nearly 1.5 million voters who cast ballots so far doesn't tell us who might be in the lead.
37 percent of those voters are Republicans, 35 percent are Democrats, and the remaining 28 percent are unaffiliated or third party voters.
Both campaigns think they're winning.
"I believe the president's not just going to get Democratic votes," Sen. Michael Bennet (D-Colo.) said. "I think he's going to do very well with unaffiliated voters and he's going to get some Republican votes as well."
"Governor Romney and Paul Ryan have great support with unaffiliated voters," said the Romney campaign's Colorado manager James Garcia. "But we have support with Democrats as well."
Obviously, both can't win here, but they have reason to think they can.
As of Friday night, President Obama led Colorado by one percentage point in the realclearpolitics.com average of polls.
That's within the margin of error: a statistical tie.
