Obligatory link of the counts of these things from past elections to prove this is nothing unusual. We're up to 50 members of Congress not seeking re-election this year, compared to 55 in 2018 and 2022, 53 in 2012, and a low of 40 in 2020 to dissuade you from drawing any conclusions that this has meaningfully increased since Trump's election.
