Ohio is called “The most Typical American State”. It’s basically the state that is the closest culturally and economically to the other 50 state of the nation. If you win it by a lot (Like Trump Did) then he should have won the election because it means he did very well in most other states. There is a reason why so many retail stores are headquartered in Columbus.
Iowa is almost only Middle Class. That is the main reason it’s chosen as one of the first states in the Primary. Trump had a landslide here meaning he should have had over performed amongst the Middle Class in every state.
Florida means he got the Senior Citizen vote and did well amongst Hispanics
