CDU Faces Leadership Crisis Amid Election Losses and Internal Opposition to Sugar Tax

The Christian Democratic Union (CDU) is grappling with a severe internal crisis as it attempts to recover from historic electoral setbacks and growing dissent within its ranks. Recent losses in three major state elections have plunged the party's polling below 20 percent, dealing a blow to party leader Friedrich Merz and prompting urgent strategic deliberations at a leadership retreat in Berlin. Generalsekretärin Franziska Hoppermann emphasized that the retreat marks the beginning of a longer recovery process focused on restoring public trust and addressing citizens’ everyday concerns. Among the proposals to regain voter support is a plan to reduce electricity taxes to alleviate high energy costs, highlighted by Rheinland-Palatinate’s Ministerpräsident Gordon Schnieder.

Complicating the CDU's internal dynamics is sharp opposition from nine state ministers overseeing CDU-led agricultural departments who have jointly demanded the cancellation of the upcoming sugar tax scheduled for July 2027. In a letter to Merz, Kanzleramtschefin Nina Warken, and Unionsfraktionschef Thorsten Frei, these ministers argue that the tax, which imposes fees on sugary drinks based on sugar content, conflicts with the coalition agreement's emphasis on voluntary measures and personal responsibility. They cite evidence from the UK showing no reduction in obesity rates due to such levies and doubt the tax’s effectiveness, advocating instead for voluntary sugar reduction efforts already underway in product formulations. Their opposition adds pressure on Merz, especially as influential CDU presidium members share skepticism about the tax.

The CDU must also navigate the political ramifications within the ruling coalition, strained by election outcomes and policy disagreements. The party faces strategic crossroads on whether to adopt a more conservative stance or pursue modernization to regain voter confidence. Merz’s leadership is under scrutiny, both due to the polling slump and discord over policy approaches, including the recent shelving of a billion-euro model proposed by coalition partner SPD.

Together, these developments illustrate the CDU’s precarious position amid shifting political landscapes. The leadership retreat intends to chart a path forward through policy recalibration and internal consensus-building to reestablish the party’s strength ahead of upcoming electoral challenges.
