Democrat Troy Jackson has won the United States Senate race in Maine, defeating Republican incumbent Susan Collins, according to reports from The Guardian and NPR.

NPR reported that the result flips a seat Collins had held for nearly 30 years, and described it as a "crucial victory" for Democrats in their push to retake the Senate majority. NPR's report on the Maine Senate race was written by Elena Moore.

The Guardian reported that Jackson toppled Collins, a five-term Republican incumbent, in what it called one of the most hard-fought contests in the U.S. midterm elections. The outlet described the outcome as one of the "biggest upsets" in the contest. Its report on the results was written by Shrai Popat and Robert Tait.

CBS News described the contest as the "tight race" between Jackson and Collins. In a video report, correspondent Jericka Duncan spoke with Maine voters about why they were supporting one candidate or the other, according to CBS News's video report.

NPR and The Guardian framed the result differently. NPR placed it within the Democratic effort to retake the Senate majority, while The Guardian emphasized Collins's length of service and the race's place in the midterm elections.

Neither NPR's nor The Guardian's summary gives vote totals or a margin of victory, so the size of Jackson's win cannot be reported from these sources. The summaries also do not describe the specific reasons voters gave in the CBS News report.
