More than a week after Election Day, there are just a dozen House races left uncalled by the Associated Press. Republicans currently have 216 seats — just two away from formally clinching the majority — while Democrats have 207. In the remaining uncalled contests, Republicans currently lead in six, while Democrats have the advantage in six.

Iowa’s 1st: Rep. Mariannette Miller-Meeks (R) leads by a razor-thin 731 votes over Democrat Christina Bohannan, but the AP has not yet called the race. (Miller-Meeks is no stranger to tight races, having won her first bid for Congress by just six votes.) The incumbent announced her bid for House Republican conference secretary, a leadership post, on Tuesday citing in part her ability to win tight battleground races. A recount is possible in this contest.

Maine’s 2nd: The state kicked off its ranked-choice voting procedures on Tuesday, and officials projected the process could take three to five days. Democratic Rep. Jared Golden led by just 726 votes over GOP nominee Austin Theriault as the process kicked off.

Oregon’s 5th: Democrat Janelle Bynum has declared victory over incumbent GOP Rep. Lori Chavez-DeRemer. But the AP has not yet called the race, despite Bynum’s lead of more than 10,000 votes. If the margin holds, the Democrat would flip control of the seat and become the first Black member of Congress from Oregon.

California’s 21st: Despite being neck-and-neck on election night with his unheralded GOP challenger, Rep. Jim Costa (D) has settled into a more comfortable position as further Democratic-friendly ballot drops have emerged. He now leads by almost four percentage points — more than 5,000 votes — in his bid for reelection in this Central Valley seat.

California’s 9th: Incumbent Rep. Josh Harder (D) has claimed victory in his reelection bid over much-touted Stockton, Calif. Mayor Kevin Lincoln (R), though the AP has yet to formally call the contest. Harder’s lead stands at more than 7,000 votes — nearly four percentage points.

Alaska at-large: A large batch of ballots posted late Tuesday did little to benefit Rep. Mary Peltola (D), who still trails GOP challenger Nick Begich by nearly 10,000 votes with more than 90 percent of ballots in. However, Begich is currently short of the 50 percent threshold to win outright, potentially triggering the state’s ranked-choice voting procedures next week.

California’s 41st: Longtime Rep. Ken Calvert (R) saw his lead over Democrat Will Rollins grow to more than 8,000 votes on Tuesday. He’s claimed victory in his reelection bid, though Rollins has yet to concede.

California’s 13th: Incumbent Rep. John Duarte (R) got several friendly ballot drops on Tuesday, keeping his lead over Democrat Adam Gray at slightly more than 3,100 votes. There’s still about 30 percent of the vote left to count, so this one could come down to the wire depending on what ballots are still out there.

Arizona’s 6th: It’s not been formally called yet, but Rep. Juan Ciscomani (R) leads Democrat Kirsten Engel by nearly 6,900 votes — or 1.8 percentage points — in this purple Arizona seat.

California’s 45th: Challenger Democrat Derek Tran keeps winning new batches of counted ballots handily and eating into the election night lead held by incumbent Rep. Michelle Steel (R). She lost another 1,600 votes from that lead on Tuesday from a batch of 9,160 votes — and Steel’s lead is now just 2,272 votes.

Ohio’s 9th: The longest-serving woman in congressional history, Rep. Marcy Kaptur (D), appears to have held onto her right-leaning seat by a hair — 1,193 votes. Her race against GOP nominee Derek Merrin has not been called by the AP, with more outstanding absentee and provisional ballots to count, but Kaptur has claimed victory.

California’s 47th: This race has also not been called, but Democrat Dave Min claimed victory on Tuesday night over GOP nominee Scott Baugh as late batches of ballots have consistently broken his way. Baugh later conceded as well. Min’s lead is now nearly 6,000 votes in what would be a major hold of an open swing seat being vacated by Rep. Katie Porter (D).

Pennsylvania Senate: Sen. Bob Casey (D-Pa.) trimmed Sen.-elect David McCormick’s advantage in the contest — called by the AP — to under 29,300 votes in the latest counting Tuesday and isn’t conceding. “I want to make sure that we can count the votes and make a determination about who won and who lost,” Casey said on Capitol Hill as he walked to vote Tuesday.

Sen. Gary Peters (D-Mich.), who headed the Senate Democratic campaign arm this cycle, said Casey “definitely” still had a path for victory. “There are a lot of votes to count,” Peters told reporters. “They have provisional ballots. They tend to break his way, so we’ll have to see how many there are and wait for every vote to be counted.”

Republicans, meanwhile, welcomed McCormick to Senate orientation Tuesday and argued Casey needed to concede.

Called races by the AP on Tuesday: Rep. Dan Newhouse (R-Wash.), Rep.-elect George Whitesides (D-Calif.), Rep. David Valadao (R-Calif.); Rep.-elect Gabe Evans (R-Colo.); Rep. Mike Levin (D-Calif.)

Note: Valadao and Newhouse are the only remaining House GOP members who voted to impeach President-elect Donald Trump over his handling of the Jan. 6 insurrection. Both won reelection on Tuesday.
