When the poll had Trump getting 44% of Hispanics, the poll is just bad.
Yes, let's unskew the polls. That always turns out really well.
I'll offer an alternative explanation -- Floridian Cuban Hispanics have typically voted Republican in greater percentages than Hispanics from other regions. That hasn't been the case this cycle because, quite frankly, Trump is toxic to ethnic minorities. However, it's possible that this group of voters is coming "home", either as a result of Rubio's candidacy or otherwise.
Or something more obvious the poll is an outlier.
Also possible, for sure. I'll just say, though, that the Atlas population tends to describe all polls highly unfavorable to their preferred candidate as "outliers". That isn't always the case -- again, look at Seltzer's final Ernst +7 poll in 2014 when the other pollsters were herding around +3ish. In fact, Ernst won by more than 8.
So am I saying Trump is necessarily really up 2 in Florida? Probably not. This is MoE stuff. And even if he was, Clinton's superior ground game probably propels her to victory there. What I am saying, though, is that this reflexive "it must be an outlier" response should be tempered.
