That's 2000 years of building up the story, painting him as something very, very special and talking to an audience who really have no idea of the history of our time. I think, if he had become a popular figure to follow, the remaining right-wing could indeed be trying to claim him - it would, after all, be nothing new.
I think your analogy to the Christian story is fairly obvious.
Of course Josephus wrote in the first century, he was initially involved as a leader during the siege of Jerusalem and subsequently joined with Titus and returned to Rome.
His history of the Jews and testimonium flavinium regarding Jesus are contested by some scholars as being partially true, nevertheless they are generally accepted by scholars as being generally true apart from the resurrection narrative. It is also true that any references anywhere are always discredited by the opposition. Origen c230ad spoke of their efficacy.
Josephus also spoke about other biblical figures including James and John the Baptist. He added light to the description in the book of Acts regarding the death of Herod Agrippa.
St.Paul’s epistles are probably the earliest scriptural documents and yes the gospel dates followed later. John being written by the apostle from his base in Ephesus (Turkey).
Much of our knowledge of historical figures comes from much later writings. There aren’t any original manuscripts of Julius Caesar but we accept later manuscripts regarding his campaigns in the Gallic wars.
You also underestimate the value of the spoken narrative in ancient times. Many writings including those regarding Buddha where not written down till much , much later.
Paul L. Maier and Zvi Baras state that there are three possible perspectives on the authenticity of the Testimonium:
1) It is entirely authentic.
2) It is entirely a Christian forgery.
3) It contains Christian interpolations in what was Josephus' authentic material about Jesus.
Paul Maier states that the first case is generally seen as hopeless given that as a Jew, Josephus would not have claimed Jesus as the Messiah, and that the second option is hardly tenable given the presence of the passage in all extant Greek manuscripts; thus a large majority of modern scholars accept the third alternative, i.e., partial authenticity. Baras adds that the third position is more plausible because it accepts parts of the passage as genuine, but discounts other parts as interpolations. Craig Evans (and separately Robert Van Voorst) state that most modern scholars accept the position that the Testimonium is partially authentic, had a kernel with an authentic reference to Jesus, and that the analysis of its content and style support this conclusion.
All in all, despite your history lesson, the only thing we gain from Josephus is that a man called Jesus lived, about the time and in the area, he is said to have lived. All else is a scholastic conjecture which we should take seriously but which lacks proof - as we would expect. I don't think the comparison with what we know about Julius Ceasar holds water. Even in comparatively recent history, we know more about Kings than the common man - or even the uncommon one.
