CNN: “Buttigieg spent much of his time on his three-day, 330-plus mile bus tour through northern Iowa preaching the need for unity, drawing a not-so-subtle contrast with Warren’s focus on fighting. It’s a new strategy that exemplifies the belief inside the Buttigieg campaign that Warren — whose growing and powerful campaign in the state is seen by Iowa operatives as outflanking former Vice President Joe Biden or Vermont Sen. Bernie Sanders — is the biggest obstacle the South Bend, Indiana, mayor faces over finishing first in Iowa.”
