Greitens won Tuesday’s GOP primary by 10 points over Brunner, his closest competitor. It had been a bitter four-way race in which Greitens and Brunner, in particular, sparred personally.

Their battle included a heated telephone argument that Brunner secretly recorded; an anonymous internet video attacking Greitens’ record as a former Navy SEAL; the involvement of shadowy federal super PACs; and the explosive “sex slave” allegation by Brunner against a top Greitens contributor.

A unity event that had been planned for Thursday to showcase Missouri’s newly minted Republican electoral slate was scuttled before it was even announced. Several sources said it was because of continuing bad blood between Brunner and Greitens.

Missouri Republican Party Chairman John Hancock confirmed Thursday that the event had been planned and then canceled. He blamed “logistical issues” in getting all the candidates together.

When asked if Brunner’s camp refused to participate, Hancock said he hadn’t talked with him.

But three other sources inside the party confirmed that Brunner’s refusal to participate is the reason the event was canceled. All three spoke on the condition of anonymity, so they could freely talk about internal party discussions.
