It was the correct move, Don Mattingly made a correct bullpen move. He put his closer in for the 7th and 8th because it was the best chance to see the 9th. Duran piped a 99.9 mph fastball that got hit. There is a litany of managers who lost with their closer standing in the bullpen.

Padres superstar reliever Mason Miller is very good, but the Cubs were one of the rare teams to hit him this year. In 2.2 innings over 3 games, the Cubs got 5 hits, a walk, and scored 2 runs, while only striking out twice. Small sample, past results are no guarantee, etc., but interesting.

In this week's Economist / YouGov Poll, Democratic candidates have a 16-point lead among likely voters. That's bigger than they ever got in 2018. My @today.yougov.com writeup, with lots of charts: yougov.com/en-us/articl...
A line chart of YouGov polling data with the headline: "Democrats have a bigger lead among likely voters in 2026 than they had with a similar group at any point in the 2018 midterms."

The chart has the sub-headline: "In the elections for U.S. Congress in November, who will you vote for in the district where you live? (% who say the Democratic candidate minus the % who say the Republican candidate)."

The chart has the note: "Note: 2026 likely voters are U.S. adult citizens who meet two criteria: (1) They either are registered to vote or say they will be registered to vote by the November elections; and (2) They either say they will definitely vote in November or say they have already voted.
The 2018 group is defined as similar to 2026 likely voters: registered voters who said they will definitely vote in that year's congressional elections. Responses of "other," "not sure," "I would not vote," and "I will not vote" are not shown."

Since St. Paul insists on making me pay attention to it's mayor's office, can someone more tuned in than I to local politics refresh me on what issues the last mayoral election turned on? Was it left vs. center-left? YIMBY/NIMBY? General discontent? Personal grievances? Ethnic coalitions?

If we could go back in time to use the national primary margin to predict the midterm House popular vote with the data available at that time, how well would it have done? Pretty well overall, with some significant misses like 2006. (Note we see no warning signs of a miss like 2006 for this year.)
Graph showing the actual House Popular vote margin compared to that predicted by the primary margin. Major trends match, and about half the time the prediction is very close.

Pompeii is a UNESCO world heritage site not because it was remarkable in its prime, but because it survived to our era untouched: one moment, preserved for all time. But future generations won't know what OUR world was like unless we do the same. This is why we MUST bury Toronto with a volcano

New in this week's Economist / YouGov Poll: a 14-point lead for Democrats among likely voters. The full analysis of our latest congressional polling: yougovamerica.substack.com/p/democrats-...
A line chart of YouGov polling data with the headline: "How many Americans plan to vote for Democrats and Republicans for Congress in 2026."

The chart has the sub-headline: "In the elections for U.S. Congress in November, who will you vote for in the district where you live? (%)."

The chart has the note: "Note: Likely voters are U.S. adult citizens who meet two criteria: (1) They either are registered to vote or say they will be registered to vote by the November elections; and (2) They either say they will definitely vote in November or say they have already voted. The displayed question has been used since the August 14 - 17, 2026 survey. Prior surveys asked the question, "If the elections for U.S. Congress were being held today, who would you vote for in the district where you live?" Responses of "other," "not sure," "I would not vote," and "I will not vote" are not shown."

Importantly, in 2033 the *original* version of The Hobbit enters the public domain. The revised version we know today — where the Riddles in the Dark chapter features a menacing Gollum & a creepy Ring, instead of the more light-hearted original — didn't publish until 15 years later.

I feel like this needs saying: we do know how you beat the Houthis. You send a large, fairly capable ground army into Yemen and force them to ground. The 'problem' is that no one with an army (USA) wants to do that and no one who might want to do that (Saudis) has a good army.
