The difference is not much. Politics definitely makes its mark on the difference. Jujutsu is a pretty loose term in the sense of a style or group of techniques. But historically, jujutsu is the base system for aiki related systems. If I remember correctly, Omiya suggests that there are three methods of technique in aikijujutsu: jujutsu, aikijujutsu, and aiki no jutsu (aiki techniques). Many aiki systems do their techniques with a jujutsu feel. Many jujutsu systems do their technqies with an aiki feel (e.g. Hakkoryu Jujutsu). There are aiki systems that concentrate solely on aiki no jutsu technques (e.g. Roppokai (they do not exclusively work on aiki no jutsu techniques, but they are world famous for their aiki not jutsu)), and some aiki arts do all three (e.g. Takeshin Aikijujutsu).
So there are no real hard line definitions here. Even Daito Ryu was called and referred to as jujutsu early on, then became aikijujutsu to delineate themselves from the rest of the pack.

I have heard Shihan Annesi say that Walley Jay {the founder of small circle ju-jutsu} do jujutsu very soft like some aiki systems.
