I want to know the answer to the following question:
Why did a regional referendum in 1996 to merge Berlin with surrounding Brandenburg fail?
All the background I'm provided with is that "A regional referendum in 1996 to merge Berlin with surrounding Brandenburg as "Berlin-Brandenburg" failed to reach the necessary majority vote in Brandenburg, while a majority of Berliners voted in favour of the merger.". Is that enough to answer the question?
Answer: yes
