DENVER -- Several congressional and legislative seats are up for grabs in the Denver metro area with Tuesday's primary election. Although turnout is expected to be light, many will be exposed to a new form of voting.

Touch-Screen voting will be the method of voting in Adams County and several other counties in Colorado. The Adams County clerk and recorder received the new machines in May, but Tuesday will be the first real test of the technology.

Electronic touch-screen voting is a type of voting that supporters say is very user-friendly, easy and secure.

"It's easy to read. It's very easy to operate and maneuver through the ballot, and we have done a lot of testing and feel quite secure with its accuracy," said Adams County Clerk and Recorder Carol Snyder

When problems with punchcard ballots sent Florida voters into the streets in 2000, Congress passed a law requiring that polling places have at least one of the electronic machines. Now, Adams County has switched over to the touch screen systems entirely.

Although one national voter group has sued, questioning the security and reliability of the machines, Snyder stands firm with its use.

"The machines, when they get out of our office are sealed, so that, again, if somebody is tampering with something or attempting to in the polling location, we will know that," she said.

Clerks have been practicing with the machines to ensure that they will work properly Tuesday.

"We did 1,200 man hours of testing and we did a mock election on these machines shortly after they were delivered, before we even decided to accept delivery of the machines from the vendor," Synder said.

She said the machines passed with flying colors.
