A Rundown of the 2020 House Primaries: Incumbent Defeats and Close Renominations

Author's Note: Since starting this blog in June, I have covered the 2020 House primaries on multiple occasions, noting races featuring incumbents with the potential to either lose their primary or face a competitive renomination. With all of the regular Congressional primaries over, I compiled a list of all of the House incumbent primary defeats and close renominations. As can be seen, I had this article ready for a long time, but planned to publish it after the Sept. 15th Delaware primary (the last of the season, exempting Louisiana's unique "jungle primary" on election day) ("2020 State"). 

     9/20/2020 UPDATE: I updated this page to mention incumbent Representative Yvette Clarke (D, NY-9), whose primary race was originally not included here, but who won their House primary by less than 30%, thus qualifying to be on the "close renominations" section. I also edited and updated the number of total close renominations (< 30.00% winning margin) throughout the article to reflect this change.
