The Free Democrats are the junior partners in Merkel’s governing ‘black-yellow’ coalition, and though Merkel would prefer to continue governing alongside the Free Democrats, their support has dropped so low that it risks missing the 5% threshold necessary to win seats in the Bundestag, the lower house of the German parliament. With the Christian Democrats holding a consistent double-digit lead over the center-left Sozialdemokratische Partei Deutschlands (SPD, the Social Democratic Party), and with voters preferring Merkel with a two-to-one margin over Social Democratic chancellor candidate Peer Steinbrück, there’s not much risk that the CDU will lose on September 22 — together with its Bavaria sister party, the Christlich-Soziale Union in Bayern (CSU, the Christian Social Union).
