Democratic primary turnout has soared in some states. Can it carry over to November?

Turnout numbers get thrown around like they mean something automatically, and every cycle somebody's party convinces itself that a good primary is a preview of a good November. It rarely works that way. Primaries pull out the most engaged, most online, most activist slice of a party. That's a different animal than the guy who votes once every four years because he's mad about grocery prices.

Democrats are welcome to feel good about this. But the last decade is littered with special-election and primary "surges" that didn't survive contact with a general electorate that cares about gas prices, grocery bills, and whether their kid can get a job after college. Energy in a primary tells you the base is fired up. It doesn't tell you a single thing about the independents and disaffected voters who actually swing House and Senate races, and who have spent the last few years souring on Democratic messaging on the economy, crime, and the border.

There's also a simpler explanation nobody in that coverage wants to say out loud: contested primaries drive turnout because there's something to fight over. Bitter intraparty fights over who represents the party's future can look like enthusiasm and still leave bruises that show up in November. A crowded, combative primary season is just as easily a sign of a party arguing with itself as a sign of a party marching toward victory.

None of that means Republicans should get comfortable. It means the smart move is to keep making the actual argument to actual swing voters instead of reading tea leaves from a primary electorate that already agrees with itself. Enthusiasm is nice. Persuasion wins elections.
