Sanders and warren split with three weeks until iowa caucuses

The long-anticipated Elizabeth Warren vs. Bernie Sanders fight has arrived. DRIVING THE NEWS: CNN reported today, "Bernie Sanders told Elizabeth Warren in [a] private 2018 meeting that

a woman can't win." Politico reported on Saturday, "Sanders’ campaign has begun stealthily attacking Warren as a candidate of the upper crust who could not expand the

Democratic base in a general election." WHY IT MATTERS: Iowa Democrats caucus in less than a month, and you can expect this budding feud to pop up at tomorrow night's debate. THE

BIG PICTURE: The two are competing to unify the far-left flank of the party. * After New Hampshire in February comes a map friendlier to Joe Biden and mountains of spending by Michael

Bloomberg and Tom Steyer. BETWEEN THE LINES: The most important line in the CNN story is that Warren’s campaign declined to comment, notes Axios' Jonathan Swan. * WARREN WAS IN THE ROOM

for Sanders' alleged comment — and, by not commenting, she allows the story to run. * ⚡"ELIZABETH WARREN RECALLED an explosive account of a meeting with Bernie Sanders in which he

said he didn’t believe a woman could win in 2020," BuzzFeed reports. * THE OTHER SIDE: Sanders denied saying this to Warren and blamed the story on "staff who weren't in the

room [who] are lying about what happened." THE BOTTOM LINE: Time spent fighting each other is time the campaigns won't spend going after Biden. GO DEEPER: Warren says she's

"disappointed" to be targeted by Sanders campaign
