DENVER -- A former election commissioner is calling for more staffing at election booths out of concern that lines may be too long on Election Day.

Some early voting locations already have long lines, but the Denver Election Commission said they are ready for Election Day and don't have plans to make changes.

However, people who are not voting by absentee ballots may need to prepare to wait in line on Nov. 7.

"We were probably here for 40 minutes," said one early voter.

This year's voting ballot is one of the longest ballots in Colorado's history, meaning voters could be spending more time at the machines.

A group headed up by former election commissioner Jan Tyler said they believe a breakdown in the voting process is imminent.

"My fear is that we will be overwhelmed at the polling sites," said Tyler.

Tyler said problems on Election Day could be alleviated by increased staff, which she said is a possibility before Nov. 7.

Tyler's group is proposing teams of election monitors at polling locations consisting of retired teachers, attorneys and other volunteers who would help with voting centers, voting machines and processing ballots.

"I also think there needs to be monitors at the election commission offices where, for example, they're storing ballots, moving ballots, (and) counting ballots," said Tyler.

Spokesman for the Denver Election Commission, Alton Dillard, said he anticipates no issues on Election Day.

"We're sorry people had to wait in line," said Dillard. "People fought and died for these rights. Hopefully standing in line on a scale of inconvenience to cast your vote and participate in this democratic process is not that great."

Some who voted early said the process with the voting machines went smoothly.

"They worked well," said Kathy Titze. "They were fairly self explanatory."

The Bill Ritter campaign has been somewhat critical of the Denver Election Commission. They said while they are encouraged by the increased number of voters, people should not have to wait in line for up to 45 minutes. The campaign said early voting centers are designed to ensure there are not long lines and said they need reassurance from the Election Commission that it will get it right on Election Day.

Bob Beaubrez's campaign said they have nothing critical to say, but that they are encouraged by the fact that election clerks are working overtime to make things run smoothly.

The Election Commission said they have been doing things differently this year than they have in the past. They pointed out the new voting centers and the voting machines.

They said people are spending more time on the machines because of the lengthy ballot and they said they are not about to tell voters they have a time limit on voting.
