AI Summary

Moderate Democratic candidates substantially outperformed leftist ones in the midterms, according to the metrics the author established months earlier.

Democratic Senate candidates as a group posted a strong average swing of 16.2 points relative to Kamala Harris’s 2024 results in their states. This undercuts claims that the electorate contains no meaningful swing voters. When the same races are examined against other statewide contests (where data were available), the pattern holds: more mainstream Democrats generally ran ahead of or closer to their co-partisans than progressive ones did.

The clearest divide appears among candidates endorsed by Bernie Sanders, used here as a practical proxy for the left. In competitive races, those candidates ranked among the weakest relative performers nationwide. None matched the relative strength shown by typical Democratic gubernatorial nominees in the same states. Charts isolating the Sanders-backed contenders (and excluding non-competitive races for clarity) show them lagging the field on both the presidential-benchmark and the intra-state comparisons. A few individual notes stand out in the data—James Talarico’s strong showing against a damaged opponent, and weaker results for figures such as Jeff Merkley—but the aggregate signal is consistent.

The author treats these results as confirmation of a long-standing finding in political science rather than a surprise: far-left positioning is broadly unpopular with the broader electorate. The practical takeaway offered is that Democrats can capitalize on Republican unpopularity by emphasizing results over ideological purity, and that seeking the endorsement of Sanders is unlikely to help. The midterm numbers, in this reading, give voters’ preferences unusual clarity.
