Republican Sen. Susan Collins, who ran unopposed, is the only GOP senator representing a state carried in 2024 by then-Vice President Kamala Harris, making her perhaps Democrats’ top target in the 2026 midterms after years of winning blue-leaning Maine. Democrat Graham Platner took control of the Democratic primary months ago, with Maine Gov. Janet Mills opting to suspend her campaign.

The expected vote is the total number of votes that are expected in a given race once all votes are counted. This number is an estimate and is based on several different factors, including information on the number of votes cast early as well as information provided to our vote reporters on Election Day from county election officials. The figure can change as NBC News gathers new information.
