The nonpartisan Cook Political Report has changed the ratings for three House contests in favor of Democrats and two in favor of Republicans following Tuesday’s primaries in California and New Jersey.

The races moving in favor of Democrats are all open-seat races where the Republican incumbent is retiring.

Democrats have long seen all three districts as pick-up opportunities.

In the race to replace Issa, Democrat Mike Levin, an environmental attorney, will face off against Republican Diane Harkey, a member of the State Board of Equalization.

In the New Jersey races, state Sen. Jeff Van Drew (D) will square off against attorney Seth Grossman (R) in the race to succeed LoBiondo. Democrat Mikie Sherrill, a Navy pilot and former federal prosecutor, will face Republican state Assemblyman Jay Webber, in the race to replace Frelinghuysen.

The two seats moving in favor of the GOP are held by Reps. Duncan Hunter Duncan HunterDCCC reserves new ad buys in competitive districts, adds new members to 'Red to Blue' program Wife of former Rep.

Hunter is running for reelection against Democrat Ammar Campa-Najjar, a former Obama administration official.

In Tuesday's open primary, Hunter won 40 percent of the vote compared to 16 percent for Campa-Najjar, who finished ahead of a more moderate Democrat, former Navy SEAL Josh Butner.

Hunter faces an FBI investigation into alleged misuse of campaign funds, but Trump won his district by a double-digit margin. Butner's failure to make the general election race could also boost the incumbent.

Cook's rating moved from likely Republican to solid Republican.

Valadao’s seat shifted from lean Republican to likely Republican after he won first place in his primary by a wide margin over Democratic businessman and engineer TJ Cox.
