Only a quick reply now on the last: Sahra Wahrenknecht was one of the two 'stars' of the PDS party (the successor of the East German state 'communist' party SED, and the East German one of the two predecessors of today's Left Party): provocative, passionate about ideology, good speaker, young, and good-looking. Thus, she is both not representative (as being a prominent intellectual/party politician; and being more the face than the holder of power within the party) and representative (of at least that half of the 57% positive about the GDR who vote for the PDS/Left Party).
