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

There are a little more than 500,000 votes left to be counted in Arizona, according to the secretary of state's office.

Officials in Maricopa County -- the state's largest -- expect to "probably" be done with their count on Monday.

Two closely watched races have yet to be decided: the Senate contest between Democratic incumbent Mark Kelly and Republican challenger Blake Masters, as well as the gubernatorial race between Democrat Katie Hobbs and Republican Kari Lake.

Some Republicans are angry that results still aren't in, but officials stressed that this is how the process set by the legislature works and that accuracy is more important than speed.

Races that fall within one-half of a percentage point or less will trigger an automatic recount.

In the hours since Republican Doug Mastriano flamed out of Pennsylvania’s gubernatorial race, losing to Josh Shapiro by double digits in a race that was somehow more lopsided than polls suggested it would be, some of the state senator’s own allies have publicly criticized the campaign.

The autopsies depict a candidate who was untrustworthy of experienced aides, blinded by his support among rural Pennsylvanians, and crippled by a refusal to engage with mainstream press. Mastriano has yet to concede to Shapiro, but he also hasn't indicated he plans to challenge the election results.

“He was nowhere in media. His campaign could not be gotten ahold of. They refused to respond to any opposition media. I think that was a huge mistake,” Jenna Ellis, a senior legal adviser to the campaign, said Thursday on Newsmax radio.

Meanwhile, Mastriano’s hardline stance on abortion was a losing strategy, said Dom Giordano, a Philadelphia-based conservative radio host who interviewed Mastriano several times throughout the fall.

“I don’t believe you can run statewide and ban all abortions, meaning even in the case of the mother’s health, rape and incest. If you say no to those things, meaning no abortions even in those cases, as Doug did, you are not going to win statewide. It is a loser,” Giordano said on his program Wednesday morning.

Elise Stefanik, the New York congresswoman who is No. 3 in the House GOP leadership, is endorsing former President Donald Trump in his yet-to-be-announced bid for the presidency.

“Republican voters determine who is the leader of the Republican Party and it’s very clear President Trump is the leader of the Republican party,” she said in a statement. “I am proud to endorse Donald J. Trump for President in 2024. I fully support him running again.”

Trump told Fox News this week that he supports Stefanik for GOP conference chair, saying, "I think she’s fantastic.”

Rep. Tony Cárdenas, a Democrat from California, officially announced his run for chairman of the Democratic Congressional Campaign Committee for the 2024 cycle on Friday. He is the first to jump in the race.

"If you elect me as the next chair of the DCCC, I promise to fight alongside you to win in 2024 so we can continue delivering for working families in the United States and adding to our great progress," he wrote in a letter to House Democrats.

Cárdenas highlighted his experience leading BOLD PAC, the campaign arm of the Congressional Hispanic Caucus. If elected as chair, he pledged to improve resources for members, build an "effective" leadership team and invest in communities of color.

Rep. Sean Patrick Maloney, the current DCCC chair, lost his reelection race to Republican Mike Lawler in what was one of the biggest victories so far for Republicans this cycle.

"In New York, we defeated the Democrat campaign chairman Sean Patrick Maloney, which will be the first time in over 40 years a DCCC chair lost his reelection," House Minority Leader Kevin McCarthy touted at an election night party in Washington, D.C.
