Our analysis

House effects: which pollster rates whom higher?

Since 24 June 2024, Infratest dimap has measured BSW on average 2.3 points below the average of the other pollsters, Institut Wahlkreisprognose has measured CDU on average 1.9 points below the average of the other pollsters, Institut Wahlkreisprognose has measured AfD on average 1.5 points above the average of the other pollsters.

Adjusted for these house effects, SPD would stand at 21.9% instead of 23.0%, BSW would stand at 6.9% instead of 6.0%, Linke would stand at 8.9% instead of 9.5%. The current average is therefore shaped by which pollsters published most recently.

Our analysis

How secure are the majorities?

Polls have errors, so we recalculate the seat distribution 3,000 times with randomly varied values. The spread for each party follows from the sampling error of the average and from how far the final polls before earlier elections actually missed. The result: the probability that an alliance would have a majority, that a party clears the threshold and who becomes the largest party. This is not an election forecast but an assessment of the current polling picture.

Brandenburg is governed by SPD and BSW. On the current polling average this alliance would win 28 of 88 seats, and would no longer have a majority.

The next Brandenburg state election is expected in autumn 2029. The term is 5 years, and anyone aged 16 or over is eligible to vote.
