On the last day of voter registration before the presidential election, several Colorado residents have reported trouble with the registration tools on the Secretary of State's website.
Under state law, voters must register no longer than 29 days before Election Day. This year, the general election is Tuesday, Nov. 6.
Andrew Cole, a spokesman for the Secretary of State, said the site has experienced very high volume recently. They've been monitoring the traffic all day and Cole said it will likely be a record number of users.
"We regret that we have experienced intermittent technical difficulties with online voter registration," said a message at the top of a web page with voter registration information Tuesday.
The final tally of users Tuesday will not be known until Wednesday, Cole said. As an example, however, he said that the number of users submitting data Monday doubled the total from the entire previous week.
