Why are Democrats attacking Pete Buttigieg?

TAFFERS ON COMPETING DEMOCRATIC campaigns have quietly snarked about South Bend, Ind., Mayor Pete Buttigieg for months. They’ve called him Sneaky Pete or Mayor McKinsey because of his ties to the business community or Cream of Pete because he’s so Midwestern white. But poll had 25% of likely caucusgoers listing him as their first choice, leading Elizabeth Warren, Bernie Sanders and Joe Biden by roughly 10 points—all that once private griping is going public. In recent weeks, high-ranking Democrats have openly attacked Buttigieg as having a flimsy résumé, uncool fan base and lack of support among voters of color and being insufficiently progressive.
