Midterm election results updates: Dems keep control of Senate with Nevada win

Republican National Committee (RNC) Chair Ronna McDaniel indicated Monday that she'll run for another term atop the GOP.

A source familiar with the matter confirmed to ABC News that McDaniel signaled her reelection bid on a call with members Monday morning, during which she said she would run if party members wanted her to and that she plans to move forward seeking reelection.

Her bid for the chairmanship, which will be decided in January, comes after disappointing midterm election results for the party.

McDaniel has served three terms atop the RNC and was first elected in 2017 with an endorsement from former President Donald Trump.

Should she win reelection, McDaniel would serve as party chair during the 2024 presidential election, which by party bylaws would force her to remain neutral during the race even if Trump, the de facto party leader, runs for a third time.

Katie Hobbs' campaign manager, Nicole DeMont, made the following statement after tonight's vote drop from Maricopa County appeared to fall short of Republican Kari Lake's hopes, not quite declaring victory for Hobbs but saying it's going that way.

"With the latest tabulation results from Maricopa, Pinal and Pima counties, Katie Hobbs is the unequivocal favorite to become the next governor of Arizona," she said. "Katie has led since the first round of ballots were counted, and after tonight’s results, it's clear that this won't change."

Hobbs, a Democrat, is leading Lake by about 26,011 votes in the yet-to-be-called race, according to unofficial county tallies so far. There are about 160,000 ballots left statewide.

Maricopa County dropped approximately 97,000 more ballots Sunday night, and Lake netted about 9,000 votes there. Just ahead of Maricopa, Pima County released another 12,000 votes, where Hobbs netted more votes. Pinal County also dropped 3,000 votes, giving Lake a slight boost.

Doug Mastriano, the election-denying candidate for Pennsylvania governor, officially conceded Sunday night to Democrat Josh Shapiro, the state attorney general, capping a week in which the state senator was silent about his defeat but never seemed poised to challenge the results, despite previously casting doubt on the integrity of the election.

"Difficult to accept as the results are, there is no right course but to concede, which I do, and I look to the challenges ahead," Mastriano wrote in a statement. "Josh Shapiro will be our next governor, and I ask everyone to give him the opportunity to lead and pray that he leads well."

Mastriano, one of the proponents of baseless claims of 2020 election fraud, suggested multiple times in the weeks prior to Election Day that he questioned the methods by which votes were counted this year.

In his concession statement, he argued that "Pennsylvania is in great need of election reform."

Nevada Sen. Catherine Cortez Masto took center stage on Sunday at the Carpenters International Training Center in Las Vegas to celebrate her victory in last week's election, which ensured Democrats will retain control of Congress.

“Thank you, Nevada. Thank you. I am so grateful to every volunteer who knocked on doors, who made phone calls, who wrote postcards and letters and who had the courage to publicly stand up and fight for our state,” she said.

“To all Nevadans, whether you voted for me or not, I will always fight for you always," she said.

Cortez Masto said her narrow win over Republican Adam Laxalt, a former state attorney general and son and grandson of former senators, was not just about her but the people of the state, working-class families and the Latinos who have continued to support her throughout her time as senator.

“Like all of you, I've never forgotten where I come from and where my family came from ... I will continue to fight for our Latino community,” she said.

More broadly, she said, "I cannot thank you enough for all of the time, commitment, effort -- everything that you put into this election. Now we celebrate, and let's continue the work.”

Laxalt has yet to speak or concede. He had acknowledged on social media that as vote-counting continued, Cortez Masto was narrowing the gap between them and could win.
