Republicans running for the House of Representatives in California, Oregon and Connecticut—states that have all leaned blue on a national level—are all ahead of or in a neck-and-neck contest with their Democratic opponents.

On Thursday, the first public poll for Connecticut’s 5th District was released and showed Republican George Logan with a one-point lead over Democratic Representative Jahana Hayes. The survey also showed Logan winning independent votes 53 percent to 38 percent.

Hayes’ district, which Biden carried in 2020 with 55 percent of the vote, has historically been a rare battleground in a state with an all-Democratic congressional delegation. With a Cook Partisan Voting Index (CPVI) rating of D+3, it is one of Connecticut’s least Democratic districts. Connecticut’s 2nd District also had a D+3 rating. The Cook Partisan Voting Index measures how strongly a district leans towards a party, the higher the number, the stronger a district leans toward that party. For example, Connecticut’s overall PVI is D+7.

It is also one of four districts where Democrats have recently slipped in the polls, suggesting that Republicans could likely see the red wave they have hoped for this midterms.

In California, Democrats in two districts are facing tough GOP challenges for a House seat. On Thursday, Politico’s Election Forecast shifted the race in California’s 25th District to “Lean Republican” and the race in California’s 49th District from “Lean Democrat” to a “Toss Up.” Biden won both districts with a double-digit lead over former President Donald Trump in 2020.

In California’s 25th District, GOP Representative Mike Garcia is now the favorite for re-election against Democrat Christy Smith, who is making her third bid to defeat Garcia. In California’s 49th District, Democratic Representative Mike Levin is in a tough contest against Republican challenger Brian Maryott, who Levin beat in 2018 with 53.1 percent of the vote.

A House seat in Oregon’s 5th District is also at risk of turning Republican. Although progressive candidate Jamie McLeod-Skinner successfully ousted moderate Democratic Representative Kurt Schrader in the primaries, her race also moved to “Lean Republican” this week.

The race between McLeod-Skinner and Republican Lori Chavez-DeRemer had previously been declared a “Toss Up” by Politico’s Election Forecast.

McLeod-Skinner previously told Newsweek that the Democrat wasn’t too focused on midterm projections, saying that “Right before we won the primary, national political pundits said the same thing.”

“Oregon’s Fifth is won on the ground, and we’re seeing great momentum as we’ve knocked on a record number of doors, doubled what my opponent could raise, and swept the Oregon editorial board endorsements,” she said.

As of Wednesday, Politico is forecasting the GOP to flip the House during the midterm elections.

“The GOP is effectively only four seats away from the majority: Republicans currently hold 212 seats, and there are two vacancies in seats where GOP candidates are favored to win in November,” Politico’s Steve Shepard said. “That leaves the party just shy of the 218 seats needed to flip the House, a feat they could accomplish even without the kind of broad electoral mandate once seen as likely.”

Newsweek has reached out to Hayes for comment.
