Sanders and Warren 'he said, she said' feud could wreck left-wing White House hopes

A tense “he said, she said” dispute between Bernie Sanders and Elizabeth Warren over what the Vermont senator said at a private dinner could destroy chances of either left-wing firebrand winning the Democratic presidential nomination.

In the last weeks before the first votes in the Democratic primaries and caucuses, the two candidates appeared poised to soon push one of their main center-left competitors, former Vice President Joe Biden or former South Bend, Indiana, Mayor Pete Buttigieg, out of the race. Sanders, 78, had bounced back from an October heart attack and topped a respected Iowa poll released last week. A New Hampshire poll released Monday showed Warren, the 70-year-old Massachusetts senator, far ahead of Buttigieg.
