WESTERVILLE, Ohio — Amy Klobuchar prides herself on being “Minnesota nice,” but the senator dropped any sweetness during Tuesday’s Democratic presidential debate, taking pointed jabs at primary competitor Elizabeth Warren.

“At least Bernie’s being honest here and saying how he’s going to pay for this and that taxes are going to go up,” Klobuchar said when her Massachusetts Senate colleague repeatedly declined to say whether middle-class Americans would face higher taxes under a “Medicare for all” single-player healthcare plan. “The difference between a plan and a pipe dream is something that you can actually get done.”
