Who is allowed to vote in Germany?
Electoral system of Germany
{'answer_start': array([-1]), 'answer_text': array([''], dtype=object)}
Elections are confidential if the voter's decision is not known to anybody else. The German Parliament's voting law even states that no elector is allowed to announce his decision in the polling station. Postal voting is problematic because the secrecy of the ballot is not guaranteed; it has therefore to be taken as an exceptional case. Since the election's more important basic principle of universal suffrage would otherwise be violated, postal votes are admissible.
