Sen. Bernie Sanders (I-Vt.) was the only major candidate to experience a measurable drop in favorability.

Former Vice President Joe Biden lost 5 points in first post-debate survey, although he still leads the field, with 33% of primary voters saying he’s their first choice.

Last week’s Democratic presidential debates provided the first real chance for many of the candidates to shake up the race, and it’s Sen. Kamala Harris (D-Calif.) who seized the moment.

Twelve percent of Democratic primary voters said Harris was their first choice for president in the latest Morning Consult survey, which collected 2,407 responses from the moment Thursday’s debate ended at 11 p.m. through all of Friday. It’s an increase of 6 percentage points from the June 17-23 poll, doubling the senator’s vote share.

That vaults her past South Bend Mayor Pete Buttigieg of Indiana and into a third-place tie with Sen. Elizabeth Warren of Massachusetts.

The post-debate survey has a 2-point margin of error, compared with a 1-point margin of error for the pre-debate survey conducted among 16,888 registered voters who indicated they may vote in the Democratic primary or caucus in their state.
