Jon Cohn has a good piece in The Bulwark on the challenges ahead for Abdul El-Sayed. The “brutal path ahead,” Jon calls it. I’ll note here that Jon is based in Michigan, despite beginning his journalism career in the East Coast cities where most political journalists are based. (In other words, his report isn’t based on parachuting into the state for a few weeks.) He notes the two, equally accurate narratives coming out of this primary battle. El-Sayed built a potent and victorious movement. Sanders-style progressive Democrats seldom win these contests in purple states. El-Sayed did. And he did it in the face of concerted opposition from the state’s Democratic establishment, the national establishment and an ocean of outside money, mostly from AIPAC.

It’s also true that Republicans will now run a viciously Islamophobic campaign against him, which will get extra traction from his association with the willfully inflammatory Hasan Piker. There’s another dynamic we’ve seen across numerous establishment-progressive battles. The Platner campaign pitched itself as appealing to working class or at least culturally working class voters who are usually unreachable by Democrats. But the polling showed that the demographic profile of Platner’s supporters looked pretty similar to what most Democrats have gotten over the last couple decades, and especially since Trump — the educated and affluent. The loose outlines of El-Sayed’s victory in Michigan look similar. Both make a pitch about young voters but they tend to appeal most to educated and downwardly mobile voters — so again, another version of standard early 21st century Democratic coalition.

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.
