A look at the midterm races that remain undecided

With Democrats set to take control of Congress after major Republican losses, some close races remained undecided. Senate contests in Alaska and Mississippi were still being counted, while results elsewhere showed Democrats making gains and Republicans winning one House seat from a Democrat.

In Mississippi, Democrat Scott Colom gained several hundred votes overnight against Republican Cindy Hyde-Smith as officials reviewed provisional ballots. Alaska still had many votes to count, including ballots from remote areas. Democrat Matt Dunlap conceded to former Maine governor Paul LePage, while Nithya Raman won Los Angeles’s mayoral race, becoming the city’s first Asian American mayor. Voters interviewed in Iowa, Texas and Kansas described economic and political concerns, as well as expectations for the incoming Democratic leadership.
