Five days before the state elections in Lower Saxony, the Debat-O-Meter accompanied the TV duel Stephan Weil/Bernd Althusmann with many media partners in Lower Saxony.

The heavyweights of North Rhine-Westphalia's state politics met on May 4, 2017 at 8:15 p.m. in the Elephant Round of the WDR: Prime Minister Hannelore Kraft (SPD), challenger Armin Laschet (CDU), Sylvia Löhrmann (Grüne), Christian Lindner (FDP), Michele Marsching (Piraten), Marcus Pretzell (AfD) and Özlem Alev Demirel (Linke). Who kept a cool head in the heated exchange? Who could convince with his political positions? Who provided the best arguments?
