the crosstabs aren't great though, there's no way DeSantis is winning almost 6/10 Hispanics
That just increases Gillum's lead.
I think you may have career options as a Democratic Dean Chambers. Yes, DeSantis is not going to win 6/10 Hispanics, but that is not how one ought to interpret polls, by picking on one or 2 crosstabs one doesn't like and selectively saying "this cross-tab is wrong in favor of x party." Error will generally not be confined to a single crosstab and will normally go in multiple partially offsetting directions.
Agreed. DeSantis only winning Whites by 7 seems off as well.
