It’s a registered voters poll, and it’s from Quinnipiac. Enough said. It’s laughable on it’s face.
Quinnipiac has been a consistent outlier in its polls against Trump, and they were absolutely horrid in the 2018 election. (They are as bad as PPP is now.)
Their final Florida poll had Nelson and Gillum both winning by SEVEN. (They both lost). They were by far the most far-left pollster in 2018. They got crushed with the actual results.
