This is an intersting scenario. With neither candidate supporting enrty into World War II, we know that the biggest loser is Churchill. Cactus Jack Garner was not the most popular Democrat, especially due to his opposition to the New Deal, civil rights and his general disdain for Roosevelt.

Senator Taft has America Firts behind him and a solidifed GOP base.
