There was no measurable shift in how Warren’s supporters viewed Sanders following their dispute over whether he said a woman can’t be president.

Sanders’ net approval fell 6 points since the Jan. 14 presidential debate, with 73% viewing him favorably and 20% viewing him unfavorably.

The latest Morning Consult polling tracking the Democratic primary found Sanders’ net favorability among likely primary voters — the share with favorable views minus those with unfavorable views — fell 6 points since before his clash with Warren, but that didn’t affect his overall first-choice support outside the survey’s margin of error. Seventy-three percent of primary voters view Sanders favorably, down 3 points from the Jan. 7-13 survey, while 20 percent view him unfavorably, up 3 points in the Jan. 15-19 polling.

Democratic primary voters’ perception of Sen. Bernie Sanders (I-Vt.) fell amid his clash with Sen. Elizabeth Warren (D-Mass.) over whether he said a woman cannot win the presidency, but it has not trickled down to their supporters.

The data tracking the first-choice support has a margin of error of 1 percentage point, while the latest favorability data has a margin of error of 2 points.

The negative drift in views put Sanders within the margin of error of Joe Biden’s favorability rating, though the former vice president still leads him in first-choice support, 29 percent to 24 percent.

The clash between Warren and Sanders began Jan. 13, a day prior to the final debate before the Iowa caucuses, when CNN reported that Sanders had told Warren in a 2018 meeting that he did not think a woman could win the White House.

Before the debate, Sanders denied the claim, but Warren issued a statement saying the reporting was true. On stage, Sanders again denied he said a woman couldn’t win the presidency, while Warren made her case about why a woman can win. When the debate was over, a microphone captured a tense interaction in which Warren said Sanders called her a liar on national television, a tape that was a key focus of post-debate news coverage.
