Takeaways from the 2016 Missouri primary
However, below the surface of winners vs. losers, incumbents and other establishment candidates experienced more challenges and significant erosion in their support, even against token opposition. In 2012, of the six statewide incumbents and seven incumbent congressmen, only Lieutenant Governor Peter Kinder and two congressmen faced a significant primary opponent. Two statewide incumbents and two congressmen ran unopposed for renomination. This year, U.S. Sen. Roy Blunt and all nine congressmen faced primary challenges. (There was no incumbent seeking reelection in five statewide offices this year.) But voters' increasing dislike for incumbents and other pros showed up in the voting percentages. Until recently, established candidates generally won close to 90% of the vote in the primary. In 2012, two statewide incumbents and two contested congressmen won 80.3% to 86.9% of the vote, while four more seriously contested races (including one member vs. member contest resulting from reapportionment) were won with margins of 59.7% to 67.0%. This year, except for uncontested Republican State Treasurer candidate Eric Schmitt, no statewide candidate and only two congressmen (Ann Wagner and Emanuel Cleaver) topped 80%. Sen. Blunt won just 72.5% of the Republican vote, while Kander, the presumptive choice for the Democratic nomination, won just 69.9%, both against token opposition.
Big win for establishment African American Democrats. In the St. Louis area, establishment African Americans challenged white city-wide candidates and also faced intra-party challenges from activists from the Black Lives Matter movement. Against whites, African American candidates swept both contested city-wide primaries (and retained a black incumbent who ran unopposed) and unseated a long-time St. Louis County Council member. The contests weren't even close. State Rep. Kim Gardner defeated her closest competitor, assistant prosecutor Mary Pat Carl (the pick of outgoing Circuit Attorney Jennifer Joyce), by more than 2 to 1 in the Circuit Attorney primary. The two black candidates outpolled the two white candidates 60-40 in that contest. Vernon Betts cruised to a 12-point win over favored 23rd Ward Alderman Joe Vaccaro for the Sheriff nomination. In north St. Louis County, State Rep. Rochelle Walton Gray routed incumbent Mike O'Mara by 22 points.
In a state representative race, incumbent Penny Hubbard held off BLM activist Bruce Franks by 84 votes, pending a challenge. In Democratic committee contests, black (or black-backed) establishment candidates held off BLM and Bernie Sanders affiliated challenges in nine of 11 contests. Sanders people had more success against establishment whites on the south side, winning contested committee seats in Wards 7 (against Brian Wahby) and 14.
Mayor Slay's diminishing influence. The Democratic contest for attorney general was a classic St. Louis vs. Kansas City showdown. St. Louis County Assessor Jake Zimmerman carried his home county big, 59%-41%, and piled up a 15,000-vote cushion there. He was endorsed by both the St. Louis Post Dispatch and St. Louis American, and in the City he snared the backing of St. Louis Mayor Francis Slay. But the City went to former Cass County (suburban Kansas City) prosecutor Teresa Hensley, 55%-45%, a larger margin than the state as a whole. Hensley did have the support of usual Slay ally, Circuit Attorney Jennifer Joyce, but Joyce's "clout" did not carry over to the contest to elect her own successor. Next spring's contest to succeed the retiring Slay should be a barnburner.
Continued growth in Republican primary vote. While both major parties drew more voters to their primaries this year than 2012, nearly all of that increase went to the Republicans. This mirrors the Republican surge in the March presidential primary, probably generated by both support of and opposition to Donald Trump. But even without a presidential contest on Tuesday's ballot, the increase in the Republican primary vote was explosive. 126,117 more voters took Republican ballots this year than in 2012 (a nearly 23% increase), compared to a more modest 10,202 increase (up 3.25%) in Democrat ballots. This year's Republican primary vote more than doubled the Democrats.' Republicans even outpolled Democrats in St. Louis County.
Rex's money was meaningless. As first noted by the Post Dispatch, three candidates who received over $10 million in aggregate campaign contributions from St. Louis philanthropist Rex Sinquefield all lost their Republican primaries. In past campaigns, Sinquefield has been a benefactor of Koster, this year's Democratic nominee for governor. Republicans may secretly hope that Sinquefield brings his 2016 "magic" to Koster this year.
Boom generation holds off Gen X (mostly).The Boom generation (a/k/a aging baby boomers) mostly held off their significant younger challengers from Generation X. Republican Boomer Mike Parson dispatched Gen Xer Bev Randles in the Lieutenant Governor race, producing an all Boomer general election contest against Democrat Russ Carnahan. Other Boomer wins over Gen Xers include Hensley over Zimmerman, Baker over Contreras, and Clay over Chappelle-Nadal.
The exception, though, was a big one. Greitens, the youngest of four GOP gubernatorial contenders, defeated two Boomers and an older Generation X. He will face Koster, also a Gen X, in the general, to succeed Boomer Jay Nixon. But they won't break any new ground, as former Republican Gov. Matt Blunt already claimed the office for Generation X in 2004.
Major inter-generational battles in November pit Gen X (nearly Millennial) challenger Kander against Boomer incumbent Roy Blunt for U.S. Senate and Republican Gen Xer Josh Hawley against Democrat Boomer Teresa Hensley for Attorney General.
