Sorry, this is not English. No one casts votes "of" something. One votes either "for" or "against" something. The correct English translation is "Ours are votes for democracy." Please start accepting this translation immediately!
The English translation is a complete hash. No native English speaker would say this. I went with "Ours are democracy's votes" which was accepted, and is maybe a little better than this, but still not something I would ever say.
