Late-Sen. Lindsey Graham’s (R-SC) sister Sen. Darline Graham Nordone (R-SC) and Rep. Ralph Norman (R-SC) will both advance to an Aug. 25 runoff to determine which Republican will appear on the ballot in November to replace Graham after his unexpected death earlier this summer. The Associated Press projected Graham’s sister would advance early in the night, but it was unclear if Norman or Rep. Russell Fry (R-SC) would clear the hurdle until moments ago when the AP determined Norman would advance as well. None of the candidates were able to secure the majority of the vote to avoid a runoff.

Three Republicans were running in Michigan’s 8th Congressional District primary. Trump in June endorsed Amir Hassan, a Navy Veteran, former Guantánamo guard, and Department of Homeland Security official. Hassan was up against Thomas Smith, a retired engineer, and Al Lemmo, an anti-abortion activist. In July, Smith suspended his campaign and endorsed Lemmo, who had decried Hassan as a “possible Trojan Horse candidate and lifelong Democrat.”

On Tuesday, Smith, who was no longer running, won a pretty clean victory over his Trump-endorsed former opponent.

Though the AP called Abdul El-Sayed the winner of the Democratic nomination for Senate in Michigan as I went to publish this post, this race turned out to be much, much closer than people expected or what polls predicted. The margin ended up being just under 1% or about 15,000 votes. We become so entranced by polls that we often fall into thinking that a candidate like El-Sayed bobbled the race at the end or Stevens mounted a comeback. There may have been some late movement. But it’s important to remember that our narrative of the race was built around polls that were simply wrong. Very wrong. It was probably always much closer than people realized. Indeed, the margin is close enough that those polls might actually have shifted the outcome of the race by depressing Stevens’ turnout or juicing El-Sayed’s. It’s a good reminder that whether you’re a volunteer, a voter, an activist, or a campaign worker you play these things out till the very end. Polls are usually right. And they’re a good guide. Except when they’re not. And this was a big “except.”
