"When the president visited Utah last month, he said I was a fighter. I've always been a fighter. I was an amateur boxer in my youth, and I brought that fighting spirit with me to Washington. But every good fighter knows when to hang up the gloves.”

The spate of recent retirements led to speculation about a widespread exodus by Republicans from Trumpland.

It is first important to note that, of the 38 GOP members of Congress planning to retire (or having already retired), 13 are planning to seek another political office (or have new roles in the Trump administration). Likewise, some members of Congress are retiring in the wake of personal scandal including Reps.

In other words, a good number of the retirements seem to be clearly related to personal considerations and cannot be attributed to a desire to seek refuge from a chaotic presidency.

However, even if we only look at the remaining retirements that number would exceed the average number of total retirements per party (11 members) per Congress since 1974 according to data gathered by Roll Call. In order to better understand why this Congress seems to be an outlier, it is helpful to look at what the political science literature has to tell us about why and when individual members of Congress opt to retire.

Jennifer Wolak, from the University of Colorado at Boulder, posited in 2007 that members of Congress pay attention to the political environment when deciding whether to hang up their hats. Wolak notes “rates of retirement are strongly influenced by context — not only the climate on Capitol Hill, but also the trends in the national political environment.”

This evidence would suggest that Republican members of Congress could be taking stock of political climate — a president under investigation, a party pursuing publically unpopular legislation, etc. — and deciding that they would rather invest their time in other ventures or, perhaps, sit comfortably on a beach somewhere.

It is also important to briefly address the number of retirements on the Democratic side of the aisle. There are 17 Democrats retiring as of this writing, a number that exceeds the norm. However, nine of these Democrats are seeking (or already assumed) another political office. Additionally, you have Sen. Al Franken Alan (Al) Stuart FrankenPeterson faces fight of his career in deep-red Minnesota district Getting tight — the psychology of cancel culture Tina Smith wins Democratic Senate primary in Minnesota MORE (D-Minn.) and Rep. John Conyers John James ConyersBiden's immigration plan has serious problems Tlaib wins Michigan Democratic primary Tlaib holds lead in early vote count against primary challenger MORE (D-Mich.) leaving as a result of personal scandal. Democrats might also be sensing a political environment — in the wake of election wins in Virginia and Alabama — primed for political advancement. History suggests that they might be right as it is usually the case that the president’s party loses seats in midterm elections.

While Republicans are retiring in mass, it is important to note that Republicans leaving these seats does not mean that those seats will turn Democratic. Indeed, in most cases, the Republican retiree will likely be replaced by another Republican (perhaps a younger Republican that will solidify that seat for years or even decades).

However, these retirements coupled with the president’s low approval rating, might suggest significant cracks in the relationship between the president and his party. Those cracks will likely become a massive chasm if the party has significant losses in the midterms.
