I think Jonathan Chait is actually pretty astonished himself, when he writes:
People who thought they knew Hillary Clinton have gazed in astonishment: What has she become? The answer is, a conservative populist.
Orrin Judd looks back on her husband’s two successful elections won with endless conservative populist rhetoric and wonders: What took her so long?
Meanwhile, Jonah Goldberg notes that Hillary’s rhetoric may sound populist in the (presumably) waning days of her campaign, it’s certainly not conservative.
