At least 6 Democratic presidential hopefuls would defeat President Trump in a head-to-head matchup if it were held now, according to a new Quinnipiac University national poll that surveyed 1,214 registered voters nationwide.

The bottom line: In descending order, former Vice President Joe Biden, Sen. Bernie Sanders, Sen. Kamala Harris, Sen. Elizabeth Warren, South Bend Mayor Pete Buttigieg and Sen. Cory Booker all polled higher in a direct one-to-one matchup with Trump.

By the numbers: The phone survey, conducted June 6–10, found...

  • Biden 53%, Trump 40%
  • Sanders 51%, Trump 42%
  • Harris 49%, Trump 41%
  • Warren 49%, Trump 42%
  • Buttigieg 47%, Trump 42%
  • Booker 47%, Trump 42%

In the Democratic primary field, meanwhile, Biden still appears to be dominating. However, he has dropped from 38% in Quinnipiac's April poll to 35% in May and 30% in June. Per Quinnipiac, Democrats or those leaning to Democrat would vote for the following (out of the 24 current candidates and 14% selecting DK/NA) ...

  • Biden: 30% (-5)
  • Sanders: 19% (+3)
  • Warren: 15% (+2)
  • Buttigieg: 8% (+3)
  • Harris: 7% (-1)
  • O'Rourke: 3% (+1)

Methodology: From June 6 - 10, Quinnipiac University surveyed 1,214 voters nationwide with a margin of error of +/- 3.5 percentage points, including the design effect. The survey includes 503 Democrats and Democratic leaners with a margin of error of +/- 5.4 percentage points, including the design effect. <br/>

Florida smashes single-day record for new coronavirus cases

Data: Covid Tracking Project; Chart: Axios Visuals

Florida reported 15,299 confirmed coronavirus cases on Sunday — a new single-day record for any state, according to its health department.

The big picture: The figure shatters both Florida's previous record of 11,458 new cases and the single-state record of 11,694 set by California last week, according to AP. It also surpasses New York's daily peak of 11,571 new cases in April, and comes just a day after Disney World reopened in Orlando.

Pelosi: Trump is "messing with the health of our children" with push to open schools

House Speaker Nancy Pelosi said on CNN's "State of the Union" Sunday that Education Secretary Betsy DeVos' aggressive push to fully reopen schools this fall is "malfeasance and dereliction of duty," accusing the Trump administration of "messing with the health of our children."

Why it matters: Trump has demanded that schools reopen as part of his efforts to juice the economy by allowing parents to return to work, despite caution from health officials that little is known about how the virus impacts children.
