AfD Leads by Widest Margin Since Election

The gap between the AfD and the governing CDU/CSU has never been wider since the federal election. Chancellor Friedrich Merz's CDU/CSU falls to 22 percent – its weakest reading since taking office. The governing coalition of CDU/CSU and SPD combined reaches only 34 percent, far short of a parliamentary majority.

The AfD's surge comes despite the so-called "firewall" (Brandmauer) maintained by all other parties, which excludes the AfD from any coalition government. This means that despite leading in polls, the AfD cannot form a government – deepening Germany's political deadlock.

SPD at Historic Low

At 12 percent, the SPD is at a historic low – having lost almost half its vote share since the February 2025 election, when it received 20.5 percent. As junior coalition partner to the CDU/CSU, the Social Democrats face mounting pressure from within their own ranks to differentiate themselves more sharply from the conservative-led government.

Context: Polls vs. Reality

Individual polls are not election results. INSA is known for producing higher AfD figures than other pollsters – the average across several current institutes puts the AfD at around 27 to 28 percent. Nevertheless, the trend is consistent: the AfD is rising, and the governing parties are losing support across all polling firms.
