Career
Neubauer was trained as an overseas buyer and undertook military service in the Bundeswehr. He backed Schönhuber in his subsequent power struggle with Franz Handlos and as such when Schönhuber became Chairman in 1985 he appointed Neubauer as secretary. The two became estranged however as Neubauer followed a more extremist path and for a while in 1990 he even forced the temporary resignation of his former mentor.
Ultimately however the leader triumphed in the struggle, forcing Neubauer out of the party and replacing him as vice-chairman with Rolf Schlierer.
The new group had the declared aim of uniting the many factions on the far-right under a single banner and initially had some success, attracting two other Republikaner MEPs and the support of the influential Nation Europa journal. He was part of a three-man leadership team with Rudolf Kendzia and Jürgen Schützinger.
Former National Purchase Diary chiefs Martin Mussgnug and Franz Glasauer were also given leading roles yet the new group made little impression in the state elections of 1992. With the German League for People and Homeland defunct Neubauer ran on the National Purchase Diary list in the German federal election, 2005 in Saxony.
