Hitler's Daughter (1990)

At the closing of WWII, with a defeat for Germany looming, Hitler smugglers out a pregnant woman. The child she's bearing? It's Hitler's, naturally. Part of a secret plot. Years later, it's time for the American presidential elections. A Nazi hunter contacts a candidate with a warning. He tells of this secret plot - and the Third Reich's plan to have Hitler's offspring capture the American presidency, just before he's killed.
