Bild online poll: 94% want the German language embedded in the German constitution

An article here on Bild discussing the possibility of entering the German language into the German constitution has a poll below with almost 18000 responses so far, and though I haven't paid enough attention to the issue to have an opinion on the matter I voted yes in order to see the results, and was surprised to see them this skewed towards the affirmative:

Bundestagspräsident Norbert Lammert will Deutsch als Sprache im Grundgesetz verankern. Halten Sie das für sinnvoll? - Bundestag President Norbert Lammert wants to embed German as a language in the constitution. Do you think that makes sense?

Ja, das ist sinnvoll. - Yes, that makes sense.

Nein, das ist unnötig. - No, that is unnecessary.

Time to pay attention to other online and real-life polls to see if this is a general trend or just unique to Bild. This one also has a weird end date, almost a year from now. Plenty of time to be altered by one site or another with an agenda for or against.
