I wanted to follow up on my post about Pat Ruffini’s deep dive about the accuracy of Senate race polling in recent cycles and whether they’ve overstated Democrats’ strength. But since I wrote that post, I’ve also gotten a few emails from friends and TPM readers about polling generally. So I wanted to combine all of this together into some general comments on polling and whether we should care about it at all.

In the wake of the big apparent polling misses in Michigan and Wisconsin, we’re seeing another wave of discussion about a purported “crisis” in polling and what we should collectively do about it or what the polling industry should do about it. Mostly, the answer is there is no “crisis” — at least in the sense of one that any of us should care about as some problem for American democracy or elections or anything else. If you’re in the polling business, it may well be a problem. But if you’re not, who cares? There might be a crisis in Swiss cheese marketing too. But if I’m not a cheese monger, why do I care?

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.
