Realigning elections

[Fmr. Pres. Duke]

I remember our AP US Government test had a question like this on it in 2007, and the correct answer was not 1896, which is the one I marked, but 1960. I guess it was in the sense that the Northeast and cities began voting Democrat reliably for the first time and since. Chicago, LA, SF, etc... when to the Republicans like Eisenhower until then, and they haven't since.
