What notable elections do you think "broke" the other side, essentially triggering them?
Presidential
For Republicans: 1948, 1960, 1992, 2008, 2020
For Democrats: 1968, 1980, 1988, 2000, 2004, 2016
Congressional Elections
For Republicans: 1998, 2006, 2018, 2022
For Democrats: 1994, 2002, 2010
Other elections:
For Democrats: NJ Midterms 1991, NYC Mayor 1993, TX GOV 1994, NY GOV 1994, CA GOV recall 2003
2018 is an interesting example because it also managed to break Democrats because of one particular swing state.
