Lauren Underwood, a 32-year-old nurse and health policy expert from Naperville, has unseated U.S. Rep. Randy Hultgren, R-Plano, in the 14th Congressional District.
In DuPage County, Underwood received about 62.6 percent of the vote, or 3,990 votes, compared to Hultgren's about 37.4 percent, or 2,383 votes, according to unofficial election results.
Underwood also claimed victory in all other counties included in the district besides McHenry.
During her victory speech, Underwood thanked Hultgren for his service and said he told her he would help her transition into her new role in the U.S. House of Representatives.
“When I travel to Washington, I will take your voices and your values with me,” Underwood said. “I am your representative. [I] work for you, and I cannot wait to get started.”
Underwood – who received a number of high-profile endorsements, including from former President Barack Obama and former Vice President Joe Biden – has said she would fight to keep the Affordable Care Act intact after having worked on it in her role as a senior adviser in the U.S. Department of Health and Human Services.
Her stances on health care also were her foundation for running for office after she felt Hultgren, who has been in office since 2010, broke a promise not to back legislation that didn't provide coverage options for patients with pre-existing conditions by voting for the American Health Care Act.
Hultgren, meanwhile, has said the American Health Care Act stated insurance companies cannot ask about pre-existing conditions as long as individuals are continuing coverage and not starting anew. He also voiced concerns over the Affordable Care Act's premium and deductible increases and lack of coverage choices.
President Donald Trump tweeted the afternoon of Nov. 6 that Hultgren is doing a great job and had his "total endorsement."
