Democrats will hold at least 50 seats come 2023. Depending on the result of the December runoff election in Georgia, the party may add to its Senate majority.
Democrats defied historical trends and defeated several candidates backed by former President Donald Trump to keep control of the Senate, providing enormous relief for President Joe Biden.
The battle for the House, meanwhile, remains too close to call.
The picture in the Senate became clear on Saturday after Democratic Sen. Catherine Cortez Masto of Nevada narrowly defeated Republican Adam Laxalt to win re-election, putting her party over the threshold, NBC News projected Saturday.
Democratic Sen. Mark Kelly of Arizona won his re-election contest in Arizona, NBC News projected Friday evening, directing all eyes to Nevada and its two most populous counties, Clark and Washoe, as mail-in ballot counting continued over the weekend.
Both Laxalt and Masters were endorsed by Trump and promoted his false claims about the presidential race he lost. Laxalt has said the 2020 election was “rigged.”
