Between LBJ's victory in 1964 and Drumpf's in 2016 there has been exactly one Presidential election that saw the Democratic candidate carry Indiana: Barry 0 in 2008. In 2012, of course, things returned to normal and Mittens carried Indiana.

As of December, 2018 Herr Drumpf enjoyed a 52% approval rating (net 8% approval). It doesn't really matter who is on the ballot in 2020, Indiana is safe for the orange baboon indefinitely.
