Tuesday is a big day for primaries, and eight states across the US are holding elections.
Here's a breakdown of the key races to watch in each state:
- California: There are nine House seats rated as competitive by CNN — and eight of them are currently held by Republicans. If Democrats are going to take back the House, they will need (and may get) a few of these to do it.
- Montana: Democratic Sen. Jon Tester will face voters for the third time and Republicans see this seat as a perfect opportunity for a flip.
- Alabama: Republican Gov. Kay Ivey is seeking her first full term (although no Alabama seat is seen as competitive this year).
- Iowa: Two-term GOP Rep. Rod Blum's race is rated as a toss-up, and Fellow sophomore Rep. David Young is also being heavily targeted by the Democratic Congressional Campaign Committee.
- South Dakota: Four-term Rep. Kristi Noem is running in the Republican primary for governor against the state's Attorney General Marty Jackley.
- Mississippi: 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.
- New Jersey: Five of New Jersey's 12 congressional seats are on CNN's competitive ratings this year.
- New Mexico: Four-term GOP Rep. Steve Pearce is running for governor, which leaves a slight opening for Democrats.
