Eight of the nine House seats rated as competitive by CNN are currently held by Republicans, some of which are in districts Clinton won in 2016. If Democrats are going to take back the House, they will need (and may get) a few of these to do it. While the Senate seat is expected to stay in Democratic hands, the primary and general election against Sen. Dianne Feinstein could turn competitive, as she will likely face a more progressive Democrat in the fall due to the state's jungle primary laws. California has a competitive governor's race to replace outgoing Gov. Jerry Brown, with top contenders in Lt. Gov. Gavin Newsom and former Los Angeles Mayor Antonio Villaraigosa, both Democrats.
Here's a look at the past and upcoming 2018 primary elections. Use the dropdown above to view results in states for which CNN has access to the election data.
Democratic Sen. Jon Tester will face voters for the third time, but this year he's coming on the heels of Trump's 21-point win in Big Sky Country. Republicans see this seat as a perfect opportunity for a flip, but party members have yet to coalesce around one candidate. Tester's significant money advantage gives him a slight edge, as CNN rates this race lean Democrat. Controversial GOP Rep. Greg Gianforte's race is currently rated as likely Republican.
Despite a surprise victory from Democrat Doug Jones in the special election for the Senate last year, no Alabama seat is seen as competitive this year for either party, including Republican Gov. Kay Ivey as she seeks her first full term.
Two-term GOP Rep. Rod Blum's race is rated as a toss-up. Blum won 51% and 54% in his northeastern Iowa district during his first two campaigns but could face his toughest race in a year that could favor Democrats. Fellow sophomore Rep. David Young is also being heavily targeted by the Democratic Congressional Campaign Committee. Both of these districts voted for President Barack Obama in 2008 and 2012 before flipping to Trump in 2016.
Three-term Republican Rep. Andy Barr's race is currently rated as lean Republican by CNN. He has won at least 60% of the vote in each election, but Democrats will likely field strong competition, which could put this seat in play.
Sen. Thad Cochran's retirement sets up a special US Senate election in Mississippi, meaning both of the state's Senate seats will be on the ballot come November. Newly-appointed GOP Sen. Cindy Hyde-Smith is facing a challenge from state Sen. Chris McDaniel in the special election race, along with multiple Democrats. McDaniel nearly knocked off Cochran in a high-profile primary race in 2014. Mississippi's House races are not seen as competitive this year.
Five of New Jersey's 12 congressional seats are on CNN's competitive ratings this year. The two open seats left by retiring GOP Reps. Rodney Frelinghuysen and Frank LoBiondo are seen as big targets for Democrats to flip. Trump's unpopularity in the Garden State could curtail the GOP's attempts to rebuild after losing the governor's mansion last year. Democratic Sen. Bob Menendez is up for a third term this year, in a race that CNN ranks as solid Democrat.
Four-term GOP Rep. Steve Pearce is running for governor, which leaves a slight opening for Democrats in this southern New Mexico district. The area trends conservative, as CNN rates this House race as likely Republican. Pearce will have a tough race to succeed Republican Gov. Susana Martinez, whose approval ratings have fallen as she ends her second term. Democratic Sen. Martin Heinrich is up for re-election.
