Wouldn't some Dominie or Jetstream be more likely?
I remember how "old" and uninformed Mr. Brandt sounded during the very first days after the wall came down. (Well ,nobody could know that much at that very moment and tell the future) Only to rev up to some high RPM to become some bright sharp mind for the next years again and somebody who really influenced the entire unification in a very positive way.
The big mistake was that his social democrat party did not really recreate the party they once had in East Germany because they now wanted to unite with the communists instead somehow. The same communist party (SED) that had put East German SPD members to jail for not wanting to unite with them before...
So SPD lost back then what they would need today to keep it from extinction.
