I really dunno about this Harvard poll:
https://harvardharrispoll.com/wp-content/uploads/2019/05/HHP_April2019_RV_crosstab.pdfBiden ... 44%
Sanders ... 14%
Harris ... 9%
Warren ... 5%
Booker ... 3%
O'Rourke ... 3%
Buttigieg ... 2%
Klobuchar ... 2%
Ryan ... 1%
Delaney ... 1%
All Others ... 0%
They can't mean this table, the other one that they say isn't the right one and has Hillary Clinton and Bloomberg has to be the right one. (Biden 34, Sanders 17, O'Rourke 8, Clinton 6, Booker 5, Buttigieg 4, Harris 4, Warren 3, Yang 2, Bloomberg 2, Klobuchar 1, Hickenlooper 1, Delaney 1, Ryan 1)
Though they did ask a couple of neat questions, one they asked Republican/Leans if they supported Trump or The Party more, 45% said Trump, 27% said The Party.
The other they asked both GOP and Dems to identify what "type" they are which is fun (they could pick up to three, first % is first choice, parenthesis is total)
