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%.

Google's chief health officer Karen DeSalvo on vaccinating America

Google on Monday became the latest Big Tech company to get involved with COVID-19 vaccinations. Not just by doing things like incorporating vaccination sites into its maps, but by helping to turn some of its offices and parking lots into vaccination sites.

Axios Re:Cap goes deeper into what Google is doing, and why now, with Dr. Karen DeSalvo, Google's chief health officer who previously worked at HHS and as health commissioner for New Orleans.

President Biden signed an executive order on Monday overturning the Trump administration's ban on transgender Americans serving in the military.

Why it matters: The ban, which allowed the military to bar openly transgender recruits and discharge people for not living as their sex assigned at birth, affected up to 15,000 service members, according to tallies from the National Center for Transgender Equality and Transgender American Veterans Association.

Sen. Rob Portman (R-Ohio) announced Monday he will not run for a third term in the U.S. Senate in 2022, citing "partisan gridlock."

Why it matters: It's a surprise retirement from a prominent Senate Republican who easily won re-election in 2016 and was expected to do so again in 2022, creating an open Senate seat in a red-leaning swing state.
