The race for a House of Representatives majority is becoming increasingly tight, with Republicans gaining ground.

The battle for control of the House of Representatives is intensifying as both parties compete for influence and crucial races remain undecided.

As of Saturday, the Republicans had a slim majority with 212 seats, while the Democrats held 200 seats, needing only 8 more seats for a majority.

To secure a Democratic majority in the House, the party must win all the closely contested races.

In swing districts and the western U.S., many undeclared seats are found in states such as Arizona, Washington, Oregon, California, Colorado, Nebraska, Iowa, Louisiana, Ohio, Maryland, New York, Maine, and Alaska.

Key House of Representative Races:

Alaska’s at-large congressional district:

In Alaska's at-large congressional district, Republican entrepreneur Nick Begich is leading Democratic incumbent Rep. Mary Sattler Peltola in a close race.

On Saturday evening, Peltola was trailing Begich 45.42% to 49.49% with 76.5% of the vote counted.

Arizona’s 6th Congressional District:

The Republican candidate has a slim lead in Arizona's 6th Congressional District race.

As of Saturday evening, Republican Rep. Juan Ciscomani was leading former Democratic state lawmaker Kirsten Engel by just 1,795 votes, with 75.64% of the vote counted, according to Planet Chronicle' Decision Desk.

California’s 13th Congressional District:

As of Saturday, the highly contested race between Republican Rep. John Duarte and former Democratic state Assembly member Adam Gray in California's 13th Congressional District remains uncalled.

With 61.73% of the vote counted, Duarte, a first-term lawmaker, led Gray by 3.25 percentage points, with 52% of the vote for Duarte and 48.75% for Gray.

California’s 47th Congressional District:

The competition to replace outgoing Democratic Congresswoman Katie Porter in California's 47th district is extremely close.

The open seat is being contested by two politicians, Republican Scott Baugh, a former Assembly member, and state Sen. Dave Min, a Democrat.

With 79% of the votes counted, Min has a slight lead over Baugh with 50.2% of the vote to Baugh's 49.8%.

Colorado’s 8th Congressional District

In Colorado's 8th Congressional District, Republican state Rep. Gabe Evans is leading Democrat Rep. Yadira Caraveo.

If sustained, Evans' lead over Caraveo would be a flip for Republicans. With 86% of the votes counted, Evans was ahead of Caraveo.

Mike Johnson, R-La., has stated that the House will remain in GOP control and has announced his campaign to maintain the gavel.

Democrats are holding out hope they could win by a razor-thin majority.

On X Thursday, House Minority Leader Hakeem Jeffries, D-N.Y., stated that the decision on who will control the House next year has not yet been made, citing ongoing ballot counting in Oregon, Arizona, and California.
