Morning Digest: Three pro-impeachment Republicans have landed primary challenges—and more could soon

The Daily Kos Elections Morning Digest is compiled by David Nir, Jeff Singer, Stephen Wolf, Carolyn Fiddler, and Matt Booker, with additional contributions from David Jarman, Steve Singiser, Daniel Donner, James Lambert, David Beard, and Arjun Jaikumar.

Leading Off

Impeachment: Following the House's recent move to impeach Donald Trump for incitement of insurrection, the 10 Republicans who voted in favor of holding Trump accountable for his actions are now almost all facing intense intra-party anger—including, in many cases, talk of potential primary challenges. Here's the latest on each:

CA-21: Republican leaders in Fresno County are enraged with Rep. David Valadao, with the local party's chair saying his organization wouldn't support the congressman "if the election were held today." But Valadao is at least somewhat insulated thanks to California's top-two primary system, which makes it exceedingly hard for partisans to oust incumbents in a primary since they'd have to finish third to miss out on the November general election—something that's never happened in a congressional race.

IL-16: Gene Koprowski, a former official with a conservative think tank called the Heartland Institute, recently told the New York Times that he was raising money for a potential campaign against Rep. Adam Kinzinger, but Koprowski​ added that he wouldn't enter the race until the Democratic-led state legislature finishes the redistricting process. Koprowski​ earned some very unfavorable notice in 2018 when HuffPost reported that he'd been charged with stalking a female colleague, and that senior Heartland officials sought to protect him.

Campaign Action

MI-03: Army National Guard veteran Tom Norton, who unsuccessfully sought the GOP nod in Michigan's 3rd District last year when it was an open seat last year, is running against Rep. Peter Meijer once again. Norton raised very little and finished a distant third with just 16% of the vote. His Twitter feed is filled with remarks like, "If there is no such thing as gender, how can @KamalaHarris be a historic female?" and "If your gay go be gay that is your right. But when you remove a body part your not a woman your still a man.  We are normalizing crazy."

MI-06: Veteran Rep. Fred Upton was censured over the weekend​ by the Republican Party​ of Allegan County​, which is one of the six counties​ in his southwest Michigan seat. Upton, a relative pragmatist in today's GOP, has often been targeted in primaries for his previous apostasies, and last year, he turned in a relatively soft 63-37 win over businesswoman Elena Oelke, who appears to have raised no money at all.

NY-24: Local Republican and Conservative Party officials are quite pissed at Rep. John Katko, though there's been no real talk of a primary challenge yet. However, Katko was already on thin ice with the Conservative Party, whom he infuriated last cycle when he cosponsored a bill that condemned Trump's ban on transgender Americans serving in the armed forces. Some (but not all) of the damage was later repaired, but loss of Conservative support could prove very dangerous: In 2018, Katko defeated Democrat Dana Balter by 13,694 votes while earning 16,972 votes on the Conservative Party line. New York's 24th is one of just two districts Joe Biden won on this list (along with California's 21st), so defections on Katko's right flank could cause him serious trouble in the general election as much as in a primary.

OH-16: Former state Rep. Christina Hagan, who sought Ohio's 16th District once before, "is not ruling out" a challenge to Rep. Anthony Gonzalez, says Politico. Hagan lost to Gonzalez 53-41 in the GOP primary in 2018, when the 16th had become open, then ran unsuccessfully in the neighboring 13th District last year, falling 52-45 to Democratic Rep. Tim Ryan.

SC-07: We've previously written about two Republicans who are considering challenges to Rep. Tom Rice, but now a third is threatening to enter the fray. Former NYPD officer John Cummings, who raised $11 million in a futile bid against AOC last year, is reportedly thinking about taking his grift show down South for a potential primary bid. Rice may be the most vulnerable Republican on this list because South Carolina, alone among these nine states, requires runoffs if no candidate secures a majority, meaning Rice can't pin his hopes of survival on winning renomination with a mere plurality.

WA-03, WA-04: Republican leaders in Washington's 3rd and 4th Districts are hopping mad and say they expect both Reps. Jaime Herrera Beutler and Dan Newhouse to face primary challenges, though no names have emerged yet. However, like Valadao, both enjoy a measure of protection thanks to Washington's top-two primary system, which works just like California's.

WY-AL: Politico reports that Air Force veteran Bryan Miller is "expected" to run against Rep. Liz Cheney, though in a brief quote, he doesn't say anything about his plans. If he does enter, however, that might paradoxically be good news for Cheney, since she already landed one credible opponent, state Sen. Anthony Bouchard, just the other day. Contra Tom Rice in South Carolina, Cheney could escape with a plurality because Wyoming has no runoffs.

Senate

GA-Sen: The Atlanta Journal-Constitution suggests that former Republican state Rep. Earl Ehrhart might be considering a bid against Democratic Sen. Raphael Warnock, who is up for re-election for a full six-year term in 2022. Ehrhart served in the state House for 30 years before retiring in 2018, making him the longest-serving Republican in the lower chamber, though he's still only 61 years old.

WI-Sen: Democratic Lt. Gov. Mandela Barnes, who previously had not ruled out a bid against Republican Sen. Ron Johnson next year, now confirms he's "given consideration" to a possible campaign, though he hasn't offered a timetable for a decision. Barnes, a former state representative, was elected on a ticket with Democratic Gov. Tony Evers in 2018 and would be Wisconsin's first Black senator.

Governors

RI-Gov: With Rhode Island Lt. Gov. Daniel McKee set to replace Gov. Gina Raimondo if she's confirmed as Joe Biden's new Commerce secretary, we were curious to know how well people who've ascended to the governorship in this manner fare when they choose to seek election in their own right. Fortunately, the University of Minnesota's Eric Ostermeier has answered this question in depth.

Since 1900, 174 second-in-command office-holders (including not only lieutenant governors but also—depending on the state—secretaries of state, state senate presidents, and state house speakers) have become governor in their own right, though only 128 were eligible to run in the following election (some, for instance, were only elevated after relevant primaries had passed). Of these, 109 chose to do so, but only a little more than half—59, or 54%—succeeded: 21 failed to win their party's nomination, while 29 lost general elections.

That's considerably lower than the overall re-election rate for governors, which from 1963 through 2013 was 75%, according to an earlier Ostermeier analysis. However, that figure includes these "elevated governors," so the actual re-election rate for governors first elected in their own right is even higher. That'll be something for McKee to think about both in terms of the Democratic primary and, should he prevail, next year's general election as well.

VA-Gov: Bob McDonnell, who was the last Republican to serve as governor of Virginia, has endorsed Del. Kirk Cox, who is hoping to break the GOP's long losing streak this fall. When McDonnell won office in 2009, that was in fact the last time any Republican won a statewide race in Virginia.

Mayors

Cincinnati, OH Mayor: Hamilton County Commissioner Denise Driehaus, a Democrat, said on Friday that she would not run for mayor this year.
