The race for the majority in the House of Representatives is on, with each party vying for power and key races yet to be held.

On Saturday, the Republicans had 212 seats and the Democrats 200. A party needs 218 seats for a majority.

The path to victory for a Democratic majority in the House of Representatives is narrowing, with the party having to overcome the most closely contested races to win power.

Many undeclared seats are in the western U.S. or in swing districts, including Arizona, Washington, Oregon, California, Colorado, Nebraska, Iowa, Louisiana, Ohio, Maryland, New York, Maine and Alaska.

California’s 47th congressional district:

The race to succeed retiring Democratic Rep. Katie Porter in California’s 47th Congressional District is also razor-thin.

Republican Scott Baugh, a former lawmaker, and Sen. Dave Min, a Democrat, are vying for the open seat.

Min has 50% of the votes, compared to Baugh’s 49.8%, with 79% of the votes counted.
