The maps below show 2018 election results in competitive U.S. House districts, as well as how parts of the districts voted in the 2016 presidential election. Among 22 competitive districts with precinct-level results available Wednesday afternoon, several flipped from Republicans to Democrats, while the GOP held onto or flipped some others. In six races a winner had not been declared.
Precincts cover small areas and can show voting trends more precisely. The circles on the maps are sized based on the margin of victory for the Democrat or Republican in each precinct. When available, they can provide more insight into what caused a district to flip — or not.

Calif. 45th District
Modest GOP lead over law professor in Orange County
Democrat Katie Porter, a law professor endorsed by Sen. Elizabeth Warren (D-Mass.), may have fallen short of the votes needed to deny Rep. Mimi Walters a third term representing this Clinton-won Orange County district. She was down 52% to 48% as of Wednesday afternoon.
Calif. 48th District
Russia-friendly Republican appears headed for defeat
Democrat Harley Rouda won a spot on the general election ballot here by 125 votes. The executive, a former Republican, had a lead over longtime Rep. Dana Rohrabacher (R), who has urged friendlier U.S. relations with Russia. Fewer than 3,000 votes separated them Wednesday afternoon.
Fla. 26th District
Moderate Republican who backed Obamacare repeal falters
Democrat Debbie Mucarsel-Powell edged Rep. Carlos Curbelo, a moderate Republican who has represented this South Florida district since 2015. Mucarsel-Powell, a former medical associate dean, turned Curbelo's vote to repeal the Affordable Care Act into a major campaign issue. Curbelo led an unsucessful effort to force an immigration-overhaul vote and had worked to distance himself from President Trump. In 2016, Hillary Clinton won this district by 16 points, and Curbelo won by 12.
Fla. 27th District
Democrats pick up open Miami seat after GOP retirement
Democrat Donna Shalala, a Cabinet secretary under President Bill Clinton, pulled this district that Hillary Clinton won by 20 percentage points into the Democratic column following the retirement of popular congresswoman Ileana Ros-Lehtinen (R). Republican Maria Elvira Salazar, a Cuban American former TV journalist, kept the race within six points by increasing Republican margins in the western part of the district relative to Donald Trump.
Ga. 6th District
Too close to call in the Atlanta suburbs
Republican Karen Handel and Democrat Lucy McBath, who became a gun-safety activist after her son was shot and killed, were locked in a virtual tie, with McBath up by about 3,000 votes early Wednesday morning. Handel won what was the most expensive House race ever in a special election in 2017. Trump narrowly won this district in 2016, which is why the maps look very similar.
Ga. 7th District
900-vote lead for Republican incumbent near Atlanta
Republican incumbent Rob Woodall appeared to have a slight edge for reelection in Atlanta's suburbs over Democrat Carolyn Bourdeaux. The area’s demographics are changing rapidly, and this is Woodall's first serious challenge since winning the seat in 2010. Trump won here by six points.
Minn. 1st District
Republican captures southern Minnesota open seat
This district President Trump won by 15 points materialized as a prime Republican pickup opportunity when Rep. Tim Walz (D) ran for governor. Walz won statewide, but Iraq War veteran Dan Feehan (D) fell just short of Republican candidate Jim Hagedorn. Hagedorn nearly bested Walz in their 2016 House race.
Minn. 2nd District
Democrats flip the script in 2016 rematch
Democratic health-care executive Angie Craig defeated Rep. Jason Lewis (R) in a rematch of their close 2016 race to represent this district that stretches from the Minneapolis suburbs into a rural area. Trump narrowly won here in 2016. Lewis faced fresh controversy over past comments as a conservative talk-radio host, this time for mocking women who said they were traumatized by unwanted sexual advances.
Minn. 3rd District
Moderate Republican wiped out in Minneapolis suburbs
Entrepreneur Dean Phillips, a Democrat, won his challenge against Rep. Erik Paulsen (R) in this suburban district that went for Clinton by almost 10 points in 2016. Paulsen, who won by almost 14 points in 2016, tried to separate himself from Trump but had trouble with his votes on Republican health-care and tax legislation.
Minn. 8th District
GOP picks up Trump district after Democrat's retirement
Republican Pete Stauber, a county commissioner and former professional hockey player, posted a 5.5 point win over former state representative Joe Radinovich (D). The Democratic representative here in this union-heavy Duluth-area district is retiring, which provided Republicans a pickup opportunity.
N.C. 2nd District
Republican survives in Raleigh suburbs
Rep. George Holding (R) warned supporters in August that he was trailing Democrat Linda Coleman, a former Wake County commissioner and candidate for lieutenant governor. Holding won his 2018 race by only five points, down from 13 in 2016. That's about how much Trump won by as well.
N.C. 9th District
Republican has fewer than 2,000 votes over challenger
Former pastor Mark Harris beat Rep. Robert Pittenger in the GOP primary and was fewer than 2,000 votes ahead of Democrat Dan McCready as of early Wednesday. This Trump +12 district stretches from Charlotte, where Harris’s margins shrunk compared with Trump's, to eastern North Carolina. Harris ran a socially conservative campaign, while McCready is positioning himself as a moderate who wouldn't vote for Nancy Pelosi for House speaker.
N.C. 13th District
First-term Freedom Caucus member withstands challenge
Rep. Ted Budd (R) won a second term against Democrat Kathy Manning, a philanthropist who says she wouldn't support Nancy Pelosi for speaker and was inspired to run by GOP health-care legislation. The Trump +9 district stretches from Democratic Greensboro, where Democratic margins increased, to rural Republican areas.
N.M. 2nd District
Republican holds slight lead in vast Trump district
Conservative state Rep. Yvette Herrell (R) led by about 2,000 votes over Democrat Xochitl Torres Small, a lawyer, as of Wednesday afternoon. The southern border district went for Trump by 10 points. It's currently represented by Stevan Pearce (R), who lost a bid for governor.
N.Y. 11th District
Army vet beats Trump-backed incumbent in Staten Island
Trump, who won here by 10 points, tweeted his support for Rep. Daniel Donovan when he faced a primary challenge. Donovan won the primary handily but lost the general election 53 percent to 47 percent to Max Rose (D), a health-care executive and military veteran. The district encompasses traditionally Republican parts of Staten Island and Brooklyn. Donovan was the only Republican in New York City's congressional delegation.
Ohio 1st District
Longtime Republican lawmaker survives challenge
Rep. Steve Chabot (R), who has represented this district since 1995 except for one term when he lost his seat, bested Democrat Aftab Pureval, the Hamilton County clerk of courts and a former Justice Department lawyer. In 2016, Trump won this district by about 7 points and Chabot won by 18.
Pa. 1st District
Trump-critical Republican hangs on near Philadelphia
Rep. Brian Fitzpatrick (R) successfully defended this slightly redrawn suburban district that overlaps with the old 8th Congressional District, which he represents. This district is more Democrat-leaning than the previous one, and he was challenged by Democratic philanthropist Scott Wallace.
Tex. 32nd District
Former NFL player ousts Republican incumbent near Dallas
Lawyer and former NFL player Colin Allred, a Democrat, successfully challenged Rep. Pete Sessions (R) in this Dallas-area suburban district that went for Hillary Clinton by two points in 2016. Sessions led Republican efforts to take back the House in 2010, a successful year for the GOP. He lost 52 percent to 46 percent in 2018 amid a successful House Democratic campaign to flip the chamber.
Va. 2nd District
In clash of Navy veterans, Democratic challenger notches narrow win
Elaine Luria, a former Navy commander, posted a 51 percent to 49 percent win over Rep. Scott W. Taylor, a former Navy SEAL and combat veteran, in this heavily military district encompassing the Eastern Shore and Virginia Beach. Taylor’s campaign was tainted when his staff members were accused of forging voters’ signatures to help add an independent candidate to the ballot. In 2016, Trump won this district by 3.4 points, and Taylor won by 22.9. Luria was able to increase margins near Norfolk and Newport News.
Va. 5th District
Distillery owner defends open seat for GOP
Republican Denver Riggleman, an Air Force veteran and distillery owner, bested ex-journalist Leslie Cockburn (D) by about 6.5 points. The conservative Trump +11 seat was vacated by Rep. Thomas Garrett (R), who announced that he is an alcoholic and would not seek reelection.
Va. 7th District
Ex-CIA operative spoils far-right congressman who once played spoiler
Former CIA operative Abigail Spanberger (D) narrowly beat Rep. Dave Brat (R), 50 percent to 49 percent. This Richmond-area district has been held by Republicans for decades. In 2014, Brat found himself on the other side of a big upset: He won a Republican primary over House Majority Leader Eric Cantor in this district that includes Richmond suburbs and more-conservative areas to the west.
Va. 10th District
Democrats turn area outside D.C. blue
State Sen. Jennifer Wexton (D) unseated two-term congresswoman Barbara Comstock (R) in this suburban Virginia seat. Comstock tried to separate herself from President Trump and his policies at key moments. The area, once reliably red, has become more competitive in recent years, with the areas closer to the District providing the boost for Wexton. In 2016, Clinton won this district by 10 points, and Comstock won by six.
