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.”

It looks like we are going to get a big test of some cardinal (possibly outdated) assumptions about American politics. I’m thinking first about the Michigan Senate race (though we might have something similar in the Wisconsin governor’s race). Several recent polls show Abdul El-Sayed holding a consistent, substantial lead over Rep. Haley Stevens. The primary is on August 4. This has been presented as a prototypical Democratic establishment vs Bernie progressive/insurgent race. And in key respects it is.

El-Sayed has all the Bernie/progressive positions. He’s run a campaign that places a heavy emphasis on the Israel-Palestine issue. And he’s centered AIPAC in his campaign in a way that even for many longtime critics and haters of AIPAC (including myself here) has a distinct whiff of antisemitic conspiracy theories. To wit, yes, AIPAC sucks. They’re a blight. They are functionally a Republican operation these days. But they are not the secret hand guiding things in the background every time there’s a bad news story or reverse of fortune for some progressive candidate, which is basically the role they’re playing in El-Sayed’s campaign.
