Deletion of Prince Daniel of Saxony

Comment: the sourcing is atrocious, and "some crazy people would like him to be King of Poland, but he doesn't believe in monarchy" (which is what one of the sources say) is not the same as "he was a candidate to become King of Poland" (apart from the fact that Poland hasn't been a monarchy for a very long time either). Are there any proper  for this  content
