The Florida poll is a snapshot of what the southern states participating in Super Tuesday may well look like next year.
Florida’s primary is scheduled for March 17, 2020 2 weeks after Super Tuesday. "Florida is a closed primary state. If you wish to vote in a partisan primary election, you must be a registered voter in the party for which the primary is being held."
Background from 538
"219 delegates will be awarded proportionally based on the results statewide and in each congressional district."
"In 2016, Hillary Clinton got 64.4% of the vote in Florida, and Bernie Sanders got 33.3%."
From the Quinnipiac Poll
"From June 12 - 17, Quinnipiac University surveyed 1,279 Florida voters with a margin of error of +/- 3.3 percentage points, including the design effect. The survey includes 417 registered Democrats with a margin of error of +/- 5.8 percentage points, including the design effect. "
Democratic Primary
"417 RV
Biden 41%
Sanders 14%
Warren 12%
Buttigieg 8%
Harris 6%
O'Rourke 1%
Booker 1%
Klobuchar 1%"
Note Sanders, Warren, Buttigieg and Harris combined are 1 point less than Biden and no other candidate reached the threshold for delegates although Sanders and Warren were within the margin of error of 15% threshold.
On impeachment
"Congress should not begin the process to impeach Trump, Florida voters say 62 - 32 percent. The only listed party, gender, education, age or racial groups supporting impeachment are Democrats, 64 - 28 percent, and black voters, 52 - 41 percent."
It is a shame that neither of FL's US Senate seats are up in 2020.
