Es geht auch um die k\u00fcnftige Ausrichtung und St\u00e4rke einer Partei, die vor allem von Lafontaine zusammengehalten worden war. Ihm war es schlie\u00dflich vor f\u00fcnf Jahren gelungen, aus der ostdeutschen PDS und der westedeutschen WASG eine Partei zu formen. Eine Partei allerdings, die zerrissen ist in Ost und West, in Regierungswillige und ewige Oppositionelle, in Realos und Ideologen, in gem\u00e4\u00dfigte und radikale Linke.

Er ist nach Lafontaine einer der bekanntesten Politiker der Linken und derzeit Fraktionsvorsitzender der Partei im Bundestag. Allerdings ist der ehemalige PDS-Vorsitzende und Rechtsanwalt nach drei Herzinfarkten gesundheitlich angeschlagen. Wahrscheinlich w\u00e4re deshalb, dass er die zerstrittene Partei nur \u00fcbergangsweise f\u00fchrt. Doch noch ist nicht klar, ob eine Person allein die Partei f\u00fchren soll oder eine Doppelspitze. Viele Linke w\u00fcnschen sich ein Duo aus einem westdeutschen und einem ostdeutschen Politiker, Mann und Frau.
