Denver Mayor John Hickenlooper promises to personally pay for parking tickets received by voters that were stuck in long lines caused by computer issues.

Many Denver voters were greeted by long lines at the polls when they went to vote on Tuesday.

The problem was compounded when the computer system used to check in voters was rebooted around 1 p.m.

At one point, some of Denver’s voting centers had a three-hour wait.

"This is the 21st Century, how hard can it be to get a database and make it accessible to 55 places? It should take 10 minutes to vote. It should take two minutes. The worst should be 10 or 15 minutes. I think that’s the standard we have to expect," said Hickenlooper.

Several voters say because of the long lines, they got parking tickets.

Hickenlooper says, at the very least, he will personally pay for any "street sweeping" tickets people might have received while trying to vote.

During this year’s election, Denver went from using precincts as polling locations to voting centers.
