New Insa poll for Berlin election: CDU narrowly ahead of the Left

The upcoming election for the Abgeordnetenhaus in Berlin is already casting its shadow. Polls at this stage are a snapshot of the mood; they do not provide a reliable forecast for election day. Voters can still change their minds before casting their ballots.

In the campaign, the parties are focusing on different priorities. Which issues will prove decisive – such as housing, transport, education, or internal security – remains open. The national political climate can also influence the mood in Berlin.

Possible coalitions after the election

Alongside the CDU and the Left, the SPD, Greens, AfD, and FDP are expected to run in the Berlin election. Coalition options after the election depend not only on the strongest forces but also on which majorities are arithmetically possible. A so-called two-party coalition is one option that could come within reach according to polls, if two parties clearly pull ahead at the top.

Smaller parties traditionally play a role in Berlin. The FDP has been fighting for years to regain seats in the Abgeordnetenhaus. Should it fail to clear the five-percent threshold, this would have consequences for possible alliances after the election.

The question of whether the Left can make the leap to the top also remains open. In earlier polls, the party had at times been in the lead; now Insa puts it just behind the CDU. The race for first place therefore remains exciting.

How meaningful are polls?

Election polls are snapshots. Figures can change before election day – for example, due to TV debates, scandals, economic developments, or the federal trend. Insa itself points out that the results are subject to statistical uncertainty.

For interpretation, comparison with earlier surveys also matters. If the CDU has been stable around 20 percent for weeks and the Left slightly below, that points more to a trend. If both figures fluctuate sharply, caution is advised in interpretation.

Overall, the poll shows: Berlin's electorate is divided on the question of which party should become the strongest force. A neck-and-neck race between the CDU and the Left makes the outcome of the election particularly open.

What consequences a close result would have depends on election day. In the event of a tie between the CDU and the Left, coalition negotiations could become complicated. A constellation that had previously not been on the table could then become possible.
