The latest election results show that Democrat Jillaire McMillan has kept her narrow lead over Republican Dan Woog in the race for House District 19 of the Colorado Legislature.

The first round of results released by Boulder County at 7:30 p.m. Tuesday showed Woog with an eight percentage-point lead over McMillan. But as of 9:20 p.m., the Democrat had pulled into a four-point lead, with 52% of the vote to Woog’s 48%.

By 12:50 p.m. Wednesday, the race remained too close to call, but McMillan still sat at 51.9% of the 40,922 counted votes, while Woog had 48.1%. House District 19 encompasses Dacono, Erie, Frederick, Firestone, east Longmont and surrounding areas, and it includes parts of both Boulder and Weld counties.

Ahead of the election, the Colorado Sun reported that the outcome of the District 19 race could determine whether Democrats would keep their supermajority in the Colorado House of Representatives. But as of Wednesday morning, the Denver Post reported, Democrats appeared on track to maintain their House supermajority.

McMillan, 46, co-founded Blue Trail Engineering alongside her husband and served as the chief of staff and director of volunteers for Mormon Women for Ethical Government.

Additionally, McMillan has served as a Parent-Teacher Association president, education foundation president and in church leadership roles. She has a bachelor’s degree and master’s degree in history, both from Boston College.

McMillan was selected this year by a vacancy committee to be the Democratic nominee for District 19 after incumbent state Rep. Jennifer Lea Parenti announced she would not run for re-election.

Although Parenti is a Democrat, McMillan has previously said she expected her race to be close since House District 19 is a swing district.

In a Facebook post on Wednesday, McMillan said while she is currently in the lead, the race isn’t over yet and there are more ballots still to be counted.

“Colorado’s electoral system is the gold standard, and I have complete trust in the professionalism, efficiency, and security of the hard workers at the Boulder County and Weld County Clerk and Recorder offices,” she wrote.

“The results, when released, will be the correct representation of the voters of House District 19. Along with you all, I am eagerly awaiting them.”

Her opponent, Woog, 46, is a real estate business owner who has served as an Erie Planning and Zoning Commissioner and an Erie Trustee. He also was once a state representative serving House District 63, which included a large swath of Weld County. Woog studied kinesiology at Arizona State University.

Woog has said he would endeavor to support businesses by cutting taxes and eliminating “unnecessary” regulations.

Woog could not immediately be reached for comment.

As of 12:30 a.m. Wednesday, 141,246 of 201,144 received ballots had been counted in Boulder County. It was not clear how many total ballots had been counted or received in Weld County.
