Rep. Suzan DelBene, D-Wash., the chair of the Democratic Congressional Campaign Committee tasked with retaking the House, tells ABC News she is "confident" but "ready for anything" this Election Day.

"I am confident we will take back the majority, but I am going to have my radar up," she told ABC News in a phone interview Tuesday morning.

"My mantra is 'be ready for anything' this entire cycle, and we are going to be ready today and after the election again to make sure every legal vote is counted," she said, pointing to the Trump administration's election-related lawsuits around mail-in ballots and threats made against local election officials.

DelBene said she will be watching House races in Virginia and Kentucky early in the night to see what to expect across the country and predicted that GOP redistricting efforts would hurt the Republican Party.

"I think we're going to see the impact of that backfiring in places like Texas 28 with Henry Cuellar," she said. "I also look at Ohio 9 and Marcy Kaptur, or Florida 14 with Kathy Castor or Don Davis in North Carolina [1st district]. I think that not only will this show that these efforts have backfired, but I would also say that this should be a warning to Republicans if they go down this path again in 2028."

Republican Secretary of State Brad Raffensperger reassured the public that Georgia's elections are secure and that results will come quickly.

"The big day is here, and Georgia's ready... We are the gold standard for election administration," Raffensperger said.

"We've seen Georgians turn out in record numbers during early voting," he added.

Raffensperger said that he expects the early vote to be uploaded by 8 p.m. Tuesday.

"Quick results tonight. You know, all of you don't want to be here till three o'clock in the morning. Neither do I," Raffensperger said. "The counties understand that, and they don't want to be there till three o'clock in the morning. So be working really hard and then uploading those results at 8 p.m."

He said that roughly 1,000 early ballots that need to be rescanned in Fulton County as a precaution will not delay the election results.

"With Fulton, approximately 1,000 ballots from advance voting will be rescanned as the equipment was taken out of service as a precaution due to screen errors. But this will not delay the results in any way," Raffensperger said.

According to Raffensperger, one precinct in Mitchell County opened 10 minutes late; he said that if "they need 10 minutes late at the end of the day, they'll be adding that."

Ohio Democratic gubernatorial candidate Amy Acton voted in Columbus, Ohio, on Tuesday morning, as the state's closely watched race for governor begins.

Acton is facing off against Republican candidate and former businessman Vivek Ramaswamy in a race jostled by controversial ads and bitter campaigning.

Speaking to reporters after casting her ballot, Acton expressed optimism about her chances of winning.

“The energy of folks, there's actual joy and hope out here, and watching people with one another, I almost feel like I'm watching it instead of being in the middle of it,” Acton said. “So it's a great uplifting feeling. We didn't get here overnight in Ohio. We have a lot of work ahead of us, so we're going to need that energy because I'm going to be asking more of everybody as we move forward.”

She also said Ohioans are struggling with costs and looking for someone to bring the temperature down.

Acton said she sees Ohio as a bellwether: “I do think we are ground zero for decency and compassion and integrity being on the ballot, and I am very hopeful that we'll see that continue to grow.”

Speaking to reporters before casting his ballot in Columbus Tuesday morning, Ohio Republican gubernatorial candidate Vivek Ramaswamy acknowledged challenges facing voters.

“It is a tough time. There's no doubt about it,” he said. “People are looking not just to make ends meet, but get ahead… This election, especially for the role of governor, just comes down to who's going to allow your family to live a better life.”

“I've been a candidate the whole time. But today, I was also wearing my hat as a voter. And as I think about every other voter who's checking that box next to my name, or frankly anything on that ballot, I want them to hold me, hold all of us on this ticket accountable to deliver for them,” Ramaswamy added after casting his ballot.

Ramaswamy did not directly discuss his opponent, Democrat Amy Acton.
