U.S. House Races, 2017-18               

  • Balance Jan. 16, 2018:  238R, 193D, 4v*.

  • Balance after Nov. 6, 2018:  tbd.

*Murphy (R-PA) resigned effective 10/21/17, Conyers (D-MI) resigned effective 12/05/17; Franks (R-AZ) resigned effective 12/08/17; Tiberi (R-OH) resigned effective 01/15/18.

Overview: Buoyed by successes in 2017, Democrats are hoping for a wave election as happened in 2010Summing up the campaign, one can say that Democrats will be running against and trying to tie candidates to President Donald Trump while Republicans will be running against and trying to tie candidates to House Democratic Leader Nancy Pelosi.  Both are unpopular.  (There was some talk among Democrats about the need to replace Pelosi, but that petered out following their successes in the 2017 off-year elections).  Republicans' "tax reform" is also bound to be a central issue in the campaign. 

Over 30 Republican Members are retiring, many more than Democrats.  Texas' congressional delegation will see big changes as eight of 36 members are retiring.  Nine of 21 committee chairs are leaving: Frelinghuysen (Appropriations), Black* (Budget), Hensarling (Financial Services), Royce (Foreign Affairs), Harper (House Administration), Goodlatte (Judiciary), Gowdy (Oversight and Government Reform), Smith (Science, Space and Technology), and Shuster (Transportation and Infrastructure).  Allegations of sexual misconduct have prompted several resignations and retirements.  An interesting situation is occurring in Pennsylvania where on Jan. 22, 2018 (less than four months before the primary) the state supreme court found that the congressional district lines violated the Pennsylvania constitution and a new plan must be adopted (+).
*Black stepped down as committee chair at the end of Dec. 2017 to focus on her campaign for governor.

  5 (4D, 1R)

In the chart above, "Running for..." columns have two rows; the top row is candidates and lower row is successful candidates.  These numbers do not include Members who announce for another office but later decide to end those campaigns and seek to stay in the House. 

"Run total" occasionally includes other offices besides U.S. Senate and Governor.  In 2010 Adam Putnam (R-FL) ran for Commissioner of Agriculture and won, in 2011/12 Ron Paul (R-TX) ran for President, in 2014 Gloria Negrete McLeod (D-CA) ran for County Supervisor and lost, and in 2016 Janice Hahn (D-CA) ran for County Supervisor and won.

Looking at these six cycles, one sees 57 Members ran for Senate and 24 were successful, while 24 Members ran for Governor and 9 were successful.

There is a definitional issue when it comes to retirements.  This category could encompass a number of different possibilities.  The narrowest definition is those who are leaving Congress at the end of their term and not seeking another elective office (straight retirements).  Next one can add those who are leaving and running for other offices.  Then, broadening the defiinition, there are those who leave before finishing their term where a special election is held and the seat filled.  Finally, there are those who are those who are defeated in primaries or die in office (involuntary retirements).  Another indicator to look at is open seats.
