I was able to find the split for the senate, but the Wikipedia article doesn't tell me about the split for the house. Is there a source I can use to find this?

  • What is your criteria for "up for grabs"? Nov 10, 2016 at 3:54
  • Now I get it, I didn't realize the term limit was 2 years. (I thought the elections were staggered like the senate) Thanks!

2018 is a mid-term election as it happens in between 2 presidential elections.

Below, sums-up what mid-term congressional elections are held:

House Elections:

  • All 435 seats hold elections.

Senate Elections:

  • 1/3 of Senate seats will hold elections
  • Around 33/34 seats will be "up for grabs"

Gubernatorial Elections:

  • 34 of the 50 U.S. states will elect their governors to four-year terms during midterm elections
  • Vermont and New Hampshire elect governors to two-year terms in both midterm and presidential elections
  • So, there will be Gubernatorial Elections in 36 states during mid-term elections.
