据美国广播公司报道，民主党人预计将保持在参议院的多数席位。
参议员凯瑟琳·科尔特斯·马斯托(Catherine Cortez Masto)周六在内华达州的预期胜利为民主党赢得了众议院，无论下个月在佐治亚州的决选结果如何，他们都获得了所需的50个席位。
这场胜利对乔·拜登总统的后半任期是一个重大的推动，无论是对他的立法议程还是他任命法官和其他官员的能力。
尽管拥有最微弱的参议院多数——50名核心成员和副总统卡玛拉·哈里斯作为打破平局的投票——民主党人在拜登的头两年里能够通过他们的一些关键优先事项。
他们获得了足够的两党支持，通过了一项全面的基础设施投资法案，这是几十年来第一项重大的枪支安全立法，也是促进国内计算机芯片生产的立法。
该党还取消了和解法案中的优先事项——这项立法只需要简单多数批准即可。民主党就是这样通过了为新冠肺炎提供资金的美国救援计划，以及对气候变化和医疗保健进行投资的通货膨胀削减法案。
周六，众议院的控制权仍悬而未决，十几场选举的计票工作仍在继续。拜登能取得多大成就还取决于共和党人还是民主党人控制众议院。共和党人已经为调查奠定基础拜登政府甚至总统的家庭成员。
不过，参议院多数党领袖查克·舒默(Chuck Schumer)周六晚些时候花了一点时间庆祝参议院的胜利。
舒默在其曼哈顿办公室举行的新闻发布会上说:“这场选举是一场胜利，是对民主党人、我们的议程、美国和美国人民的胜利和证明。”
“美国人民拒绝了——坚决拒绝了——共和党人想要把我们的国家带入的反民主、独裁、肮脏和分裂的方向，”他补充道。
参议院的命运只取决于少数几个关键州，包括亚利桑那州和宾夕法尼亚州。该党的政治重量级人物，包括拜登和前总统巴拉克·奥巴马，在最后几周大力开展竞选活动，试图激发热情。
民调显示，共和党在竞选的最后阶段赢得了选民的支持，但民主党取得了胜利。
民主党参议员马克·凯利被击败的亚利桑那州的共和党人布莱克·马斯特斯。宾夕法尼亚的种族被预测在大选之夜，民主党人约翰·费特曼击败了名人穆罕默德·奥兹博士，赢得了即将退休的共和党参议员帕特·图米的席位。
佐治亚州民主党现任参议员拉斐尔·沃诺克和共和党参议员赫歇尔·沃克将于12月6日进行决选。两位候选人都没有获得超过50%的选票，但沃诺克以49%比48%领先沃克。
参议院少数党领袖米奇·麦康奈尔。今年早些时候，通过质疑“候选人素质”，降低了对红色浪潮的预期。虽然他没有提到任何候选人，但这一轮更具争议的共和党提名人中有佐治亚州的沃克和宾夕法尼亚州的奥兹。
“我认为众议院翻案的可能性比参议院更大。参议员竞选就是不一样，”共和党领袖说。"候选人的素质与结果有很大关系。"
然而，根据OpenSecrets的数据，麦康奈尔的参议院领导基金在这个周期花费了至少2.3亿美元，试图夺回众议院的控制权。
根据OpenSecrets的数据，参议院多数党PAC，一个与舒默结盟的团体，至少花费了1.55亿美元。
Democrats projected to keep control of the Senate
Democrats are projected to keep their majority in the Senate, ABC News reports.
Sen. Catherine Cortez Masto's projected victory in Nevada on Saturday clinched the chamber for Democrats, giving them the 50 seats needed regardless of the outcome of next month's runoff election in Georgia.
The win is a major boost to President Joe Biden in the second half of his term, both for his legislative agenda and his ability to appoint judges and other officials.
Despite having the slimmest of possible Senate majorities -- 50 caucus members and Vice President Kamala Harris as the tie-breaking vote -- Democrats in Biden's first two years were able to pass some of their key priorities.
They gained enough bipartisan support to pass a sweeping infrastructure investment bill, the first major gun safety legislation in decades and legislation boosting domestic production of computer chips.
The party also checked off priority items in reconciliation bills -- legislation that only requires a simple majority for approval. That's how Democrats passed the American Rescue Plan, which provided COVID-19 funds, and the Inflation Reduction Act, which made investments in climate change and health care.
Control of the House was still up in the air on Saturday, as vote counting continued in more than a dozen races. How much Biden will be able to accomplish will also hinge on whether Republicans or Democrats control the lower chamber. Republicans have already laid the groundwork for investigations of the Biden administration and even members of the president's family.
Still, Senate Majority Leader Chuck Schumer, D-N.Y., took a moment late Saturday to celebrate the Senate win.
"This election is a victory -- a victory and a vindication for Democrats, our agenda, and for America and for the American people," Schumer said as he held a press conference at his Manhattan office.
"The American people rejected -- soundly rejected -- the anti-democratic, authoritarian, nasty, and divisive direction that MAGA Republicans wanted to take our country in," he added.
The fate of the Senate came down to just a handful of battleground states, including Arizona and Pennsylvania. Political heavyweights for the party, including Biden and former President Barack Obama, hit the campaign trail hard in the final weeks in an attempt to stoke enthusiasm.
Republicans gained ground with voters in those races in the final stretch of the campaigns, polling showed, but Democrats emerged victorious.
Democratic Sen. Mark Kelly defeated Republican Blake Masters in Arizona. Pennsylvania's race was projected on election night for Democrat John Fetterman, who won against celebrity Dr. Mehmet Oz and flipped the seat opened by retiring Republican Sen. Pat Toomey.
Georgia's Senate race between Democratic incumbent Raphael Warnock and Republican Herschel Walker is heading to a runoff on Dec. 6. Neither candidate received more than 50% of the vote, but Warnock led Walker 49-48%.
Senate Minority Leader Mitch McConnell, R-Ky., earlier this year tempered expectations of a red wave by questioning "candidate quality." While he didn't name any candidates, among the more controversial Republican nominees this cycle were Walker in Georgia or Oz in Pennsylvania.
"I think there's probably a greater likelihood the House flips than the Senate. Senate races are just different," the GOP leader said. "Candidate quality has a lot to do with the outcome."
Still, McConnell's Senate Leadership Fund spent at least $230 million this cycle trying to win back control of the chamber, according to OpenSecrets.
The Senate Majority PAC, a group aligned with Schumer, spent at least $155 million, according to OpenSecrets.
