I somehow doubt that a state that last voted Democratic in 1964, voted for both Wilkie and Dewey, and was only won by Grover Cleveland between the Civil War and 1912. Indiana is one of those Republican states that has been Republican since, basically, the beginning of time.
This isn't true- Indiana was a crucial swing state in the latter half of the nineteenth century. Seymour nearly carried it, and he was beaten pretty soundly by Grant. Tilden carried it. Hancock lost it by a point. Bryan came fairly close in 1900 and
very close in 1908.
It was more or less a tossup after the Civil War, and it's sheer luck that the Republicans managed to carry it so often.
Not that I'm arguing Indiana will shift, understand-
now its political leanings are set in stone, and it's a Kansasesque machine state.
