Maybe next election, given current trends.
I'm not sure about this. If anything, Florida appears to be moving right. Pennsylvania is as well, but it seems like the easiest 2X Obama-Trump state for Democrats to win back. For now, the influx of retirees and final decline of the anomalously Dem FDR generation is clearly winning over ethnic diversification. It also doesn't help that Obama decided to pal around with Cuba.
The Puerto Rico situation could change this, but the only way I could see it happening in 2020 is if PA swings hard right like Florida did for Bush in 2004.
