Democrats on course for largest House majority in decades

Democrats have secured a majority in the US House of Representatives and could finish with their largest number of seats in decades, network projections indicate.

NBC News' Decision Desk estimated Democrats would end up with about 258 seats to 177 for Republicans. CBS News estimates suggested the party could win 259, though it cautioned the final number could be lower. With 367 of 435 races called, Democrats had 228 seats, according to The Guardian.

NBC News reported that four Republican incumbents were defeated in Pennsylvania: Brian Fitzpatrick lost to Bob Harvie, Ryan Mackenzie to Bob Brooks, Rob Bresnahan to Paige Cognetti and Scott Perry to Janelle Stelson. In Virginia, former Democratic congresswoman Elaine Luria defeated Jen Kiggans, and in New Jersey Tom Kean Jr lost to Rebecca Bennett.

CBS News noted that redistricting in states including Texas and Florida did not prevent Republican losses. Several dozen races remain uncalled.
