Where are you getting your data from?

NYS 2016 Hillary: 4.5 million (59.38%) Trump: 2.8 million (36.75%)

NYS 2020 Biden: 5.2 million +0.7 mil (60.87% +1.49%) Trump: 3.2 million +0.4 mil (37.74% +0.99%)

Overall a blue shift in NYS. Did you add working family party votes to the total (and I think biden also got other 3rd party lines in NY that year) or just raw dem votes? NYS has fusion voting so raw dem votes are not the total votes received - candidates run on and receive votes from multiple lines. *edited to make formatting look a little better
