You should find and dig around in WW2-era newspaper archives. It's eye opening. If online resources are scarce, then there's microfiche and physical copies themselves. What I found, in "flyover country" it was "get those dirty Japs and Nazis!", while on the west and east coasts, particularly the cities, there was carping about bringing our boys home and "Roosevelt's war". Kinda funny how much things change, they stay the same don't they.
