Denver's runoff election results could change Thursday.

Stop. Michael Hancock will still be mayor.

However, the race for Clerk and Recorder is so close, it's possible that what normally happens after an election may get more attention.

The reason election results are "unofficial" for more than a week is because there is a grace period to resolve issues and receive certain ballots that come in late.

Military and overseas ballots are accepted for up to eight days following Election Day. Those votes are then added to the results we see on Election Day.

There are also the ballots that are rejected for reasons that can be fixed and added to the total.

Ballots can be rejected because of a signature discrepancy, meaning a signature that doesn't match your signature that the clerk's office has in your file.

Maybe you forgot to sign your ballot.

Or maybe you're a new voter who needed to provide ID your first time around.

The clerk and recorder's office sends those voters a letter letting them know that there was an issue with their ballot, that it hasn't counted and that it can be fixed within the eight-day cure period.

Those voters can sign a form and send it back to the clerk's office and their vote will be counted.

This happens for every election. You just don't hear about it unless there's a close race because the candidates get involved in trying to get a voter to cure their ballot.

"They're kind of spread out all over the city, so we're making sure that we're driving by and making sure we're visiting each one of these households, to make sure that the vote that they cast, is indeed, counted," said Clerk and Recorder candidate Paul Lopez.

"From my perspective, as someone who's running for clerk because I care about everyone participating in the elections, we don't ask who you voted for, we don't care who you voted for, we're just helping people finalize this final step in the process," said Clerk and Recorder candidate Peg Perl.

The unofficial results have Lopez leading Perl by 315 votes.

There were 959 votes that were not counted because of signature or ID issues.

That's 959 votes that could be for Lopez or Perl or neither that haven't been counted.

Lopez, his campaign staff and volunteers have been going door-to-door and calling those 959 voters.

"We don't ask who you voted for. All that matters to us is that you voted, and we want to make sure that that ballot counts," said Lopez.

Perl has her staff and volunteers also making calls and going door-to-door.

"I am personally not. As the candidate, I felt that it was a little intimidating and overbearing to be the one to go and talk to voters," said Perl. "It doesn't matter who you voted for. I didn't want to be the one showing up at their door and have a voter think, 'oh, I didn't vote for her, I feel bad.'"

As of Wednesday afternoon, 237 votes have been cured and will be added to the totals on Thursday morning.

If the race is within one-half of one percent of the winning vote total, there will be an automatic recount.

As of Election Day, Lopez had 72,405 votes. If his vote total doesn't change, an automatic recount would happen if the difference is 362 votes.

The difference is 315.

Which draws more attention to the 20,775 who turned in a ballot and did not choose Lopez or Perl. They left the race blank.

"Having the right to vote is also having the right not to vote in races, and you never know, sometimes people just don't feel informed about the choices. Sometimes people can't decide. Some people don't know about it," said Perl. "I have no hard feelings toward anybody who ended up leaving this race blank. I just hope that, in general, by the next time it rolls around four years from now, maybe people feel that they're more informed and that they want to participate."
