Matt Bai: “For Clinton, the smarter move — and, I think, the one closest to where she really is politically, once you strip away all the artifice of the primaries — is to choose a more conventional running mate with a younger, more comfortable vibe. A swing-state senator like Virginia’s Tim Kaine or Colorado’s Michael Bennet could help reassure independents and maybe even draw some anti-Trump Republicans, too.”
“Or Clinton could do what she’s pretty good at, which is to split the difference. She might gravitate toward Sherrod Brown, the populist Ohio senator, who’s every bit the class warrior that Warren is, but with a less condescending touch and a proven ability to win working-class votes.”
“The larger point is that Clinton’s choice isn’t just about winning in November. It’s also a window into how she intends to govern.”
