2020 Democratic candidate Sen. Kamala Harris received a significant bump in favorability following her debut on the debate stage last week, according to two polls conducted by Morning Consult and CNN.

Why it matters: Polls determine candidates' eligibility for the debate stage. For the second debates, candidates must have reached 1% in three DNC-approved polls to get a slot on either July 30 or 31.

The big picture: Most political commentators believe Harris had an all-around strong debate showing, but it was her now-viral challenge of former Vice President Joe Biden's opposition to federally mandated busing in the 1970s that really set her apart. Harris raised more than $2 million from 63,000 donors in the 24 hours after the debate, with tweets mentioning her handle generating 23% more interactions on Twitter than Mayor Pete Buttigieg, the next highest candidate.

By the numbers, according to Morning Consult:

  • Joe Biden: 33% (-5)
  • Bernie Sanders: 19% (0)
  • Kamala Harris: 12% (+6)
  • Elizabeth Warren: 12% (-1)
  • Pete Buttigieg: 6% (-1)
  • Cory Booker: 3%
  • Beto O’Rourke: 2% (-2)
  • Andrew Yang: 2%

By the numbers, according to CNN:

  • Joe Biden: 22% (-10)
  • Kamala Harris: 17% (+9)
  • Elizabeth Warren: 15% (+8)
  • Bernie Sanders: 14% (-4)
  • Pete Buttigieg: 4% (-1)
  • Cory Booker: 3%
  • Beto O'Rourke: 3% (-2)
  • Amy Klobuchar: 2%

Methodology: Morning Consult surveyed 2,407 Democratic primary voters immediately following the first Democratic primary debate. The interviews were collected June 27–28 and have a margin of error of +/- 2%.

CNN conducted their poll through SSRS from June 28-30, surveying 1,613 adults with a margin of error of +/- 3%. For the subsample of 656 Democrats and Democratic-leaning independents who are registered voters, the margin of error was +/- 4.7%.

Debate commission co-chair: We don't expect moderators to fact-check candidates

Presidential Debate Commission co-chair Frank Fahrenkopf Jr. said Sunday he doesn't expect Fox News anchor Chris Wallace or any of the other moderators to fact-check President Trump or former Vice President Joe Biden at the debates.

What he's saying: "There's a vast difference between being a moderator in a debate and being a reporter who is interviewing someone." Fahrenkopf Jr. said on CNN's "Reliable Sources."
