A recent poll of Maryland residents showed that the majority think this is a northern state. Obviously, they have never lived in the north. I grew up in New York and suburban Philadelphia. One thing that disqualifies Maryland from being a northern state is there terrible handling of snow. They close schools on many days I know I would have gone to school in New York. Pathetic.
I also think there are a lot more people here with ancestors from the south than from the north. When I interviewed people in the 1970s when I worked for the government, I think I spoke to about 10 times as many people born south of Baltimore than born north of here.
Another reason Maryland is a southern state is that we had Confederate monuments which were recently removed. You didn’t see them up north (except in places like the Gettsyburg battlefield).
Sad!
