On Tuesday, North Carolina Republican Rep. Robert Pittenger lost his battle for renomination to pastor Mark Harris. He is the first House incumbent to lose a primary challenge this year. With this involuntary retirement, there are now 54 current members of the U.S. House not running for re-election to their seats this November.
Of the 54 departures, 11 were running for U.S. Senate at the beginning of the week. That number is now eight, as three of the four that had primaries on Tuesday were defeated. In Indiana, Reps. Todd Rokita and Luke Messer were defeated, as was Rep. Evan Jenkins in West Virginia. Only Rep. Jim Renacci of Ohio moved on to the general election.
The full list of retirements has been updated. Note that one of the 54, Rep. Charlie Dent of Pennsylvania is expected to resign in the upcoming weeks.
