A number of races in the midterm elections will help determine who has control of the House of Representatives.

Republican Congressman Chris Collins is being challenged by Democrat Grand Island Supervisor Nate McMurray.

Collins was indicted in August on federal charges of insider trading and lying to the FBI. He has always maintained his innocence, and his trial is set for 2020.

Control of the Governor’s Mansion is also at stake today.

Andrew Cuomo is running for his third term. That would match his father, Mario Cuomo, who served three terms in the 80s and 90s.

Republican Dutchess County Executive Marc Molinaro is challenging Cuomo, and polls released over the weekend show Molinaro gaining ground.

There are also several third-party candidates, including Larry Sharpe, Howie Hawkins and former Syracuse Mayor Stephanie Miner.

The extra attention on this year’s midterm, billed as the most important in decades, has also focused efforts on ballot security.

Erie County election officials say none of the electronic voting machines in New York State are hooked up to the Internet, which limits cyber attacks on equipment.

Polling site volunteers also watch the machines closely. Inspectors will call in the results, and a chip from the machine is tracked and brought in person to the Board of Elections.

Erie County Board of Elections Commissioner Ralph Mohr said “We’ll take that chip, we’ll match it up against the results that were called in and that way, if there was an error in the call, those get corrected.”

Erie County Democratic Committee Chairman Jeremy Zellner said “Our ballots are paper. They get counted when they go in the machine and they’re there for us to count after when we do our reconciliations.”

The Erie County Board of Elections expects a high voter turnout today. About 580,000 people are registered to vote in Erie County.

Polls are open from 6 a.m. until 9 p.m.
