Democrat Ben McAdams held the line against Rep. Mia Love as the ballot counting process in Utah stretched into Wednesday.
McAdams has a razor-thin lead of 1,229 votes over the incumbent Republican in the race for the 4th District, the Salt Lake Tribune reported. As it stands, McAdams has captured 50.3 percent of the vote, and Love has garnered 49.7 percent.
Both campaigns told the paper they are closely monitoring the results and optimistic about how the final tally will shake out.
The law in Utah holds that a losing candidate can request a recount if the margin of victory falls at a quarter of a percentage point or less.
Ballot counters will release new numbers Friday, a county official said.
