House Retirements 2018

In every election cycle a certain number of representatives retire leaving behind open seats for their parties to defend. In 2018, the number of open seats, especially Republican held seats, is unusually large. Here are the number of retirements in recent years:

Year Democrats Republicans
2016 18 25
2014 17 25
2012 22 19
2010 17 20
2008 6 27
2006 9 18

This year 19 Democrats and 38 Republicans are retiring at the end of their current term.
Here are the announced retirements so far, sorted on PVI (Partisan Voting Index).
Any seat between R+5 and D+5 is a swing district that has to be fought over, even more so
if occupied by the other party. Pennsylvania districts are not included since the courts redrew the entire map this year.

In addition, there are seven vacancies in the House. All require special elections. However, some of these will be held on election day (MI-13, PA-07, and PA-15), which is effectively the same as an open seat, since no incumbent will be running. For this reason, we have counted these as retirements, rather than resignations.

Furthermore, special elections will be held in OH-12 on Aug. 7, TX-27 on June 30, and in OK-01 and NY-25 on dates to be determined.
