Midterm election results updates: Dems keep control of Senate with Nevada win
Catherine Cortez Masto’s victory in Nevada clinched the chamber for Democrats.
The 2022 midterm elections shaped up to be some of the most consequential in the nation's recent history, with control of Congress at stake.
All 435 seats in the House and 35 of 100 seats in the Senate were on the ballot, as well as several influential gubernatorial elections in battleground states like Arizona, Georgia, Pennsylvania and Wisconsin.
Democrats were defending their narrow majorities in both chambers and retained control of the Senate, though control of the House isn't yet clear. But a Republican flip of the lower chamber would be enough to curtail most of President Joe Biden's legislative agenda and would likely result in investigations against his administration and even his family.
Key updates:
Polls now closed in 25 states
Arkansas is the latest state to close its polls, with polls now closed in 25 states plus D.C.

These three races will determine balance of power in the Senate: Klein
Senate races in Georgia, Nevada and Pennsylvania will determine which party controls the chamber next year, according to ABC News Political Director Rick Klein.
Whoever wins the two of those three are probably going to win the whole Senate,” Klein said as the first race projections started to come in from across the country.
The best chance for Democrats to pick up a seat is in Pennsylvania, Klein said, where Democrat John Fetterman faces celebrity Dr. Mehmet Oz.
"In Nevada, that's probably going to be Republicans’ best chance,” Klein said. “They see Sen. Catherine Cortez Masto as the most vulnerable Democrat anywhere on the map."
Here’s what to expect if Republicans retake majority control in the Senate.
