[H. Ross Peron]

I'm surprised by some of the numbers-40% of blacks voting for the Democrats in the North a generation or less from the Civil War?

On the state level, most Northern states were strongly Republican except for New Jersey, Indiana, Connecticut, and New York. I'm guessing New York was due to all the immigrants in NY, Indiana due to the butternut population, and New Jersey due to its closeness to the Mason-Dixon Line. However I'm not sure how to explain Connecticut...
