Early voting is officially underway in New York's state primaries, giving voters their first opportunity to cast ballots in several key races that could help shape November's general election.

In Suffolk County, voters were introduced to a new voting experience this election cycle. For the first time, residents are using updated voting machines that combine paper ballots with touchscreen technology. After inserting their ballot, voters make their selections on a screen before submitting their vote.

Some voters said the process was simple and easy to follow.

"The machine tells you everything you need to do," said Arlene Bernhard. "It was so easy."

Some voters said the process took a little getting used to.

"I put in the name I wanted, and I was waiting for something to come up, but nothing did," said Pam Ferencsik. "So, I ended up just casting a ballot."

As for security, the manufacturer says it's impossible to add, modify or invalidate a vote and that each machine has a built-in provision to apply tamper-evident seals for detection and unauthorized access.

Meanwhile, voters in Nassau County continue to use traditional paper ballots.

Several closely watched races are on the ballot this primary season. In New York's 3rd Congressional District, incumbent Democrat Tom Suozzi faces challenger Danielle Welch. On the Republican side, Mike Lipetri and Greg Hach are competing for their party's nomination.

Other races attracting voter interest include contests in the 1st and 4th Congressional Districts, along with a three-way primary race for state comptroller.

For many voters, the importance of those races was enough reason to vote early.

"Sometimes you get multiple candidates running in the primaries, and you really want the person you know to get in," said Syosset voter Larry Hass.

Hass added that voting remains a fundamental part of civic participation.

"It's part of democracy. It's our right. I think we should exercise that right."

Early voting runs through June 21.
