I don’t think there’s an all-encompassing answer to that. Organizations, parties included, are simply not without their inner contradictions and don’t behave as a single organism. We’ve butted heads on pretty much that issue before. :)

I’ll also note that in many cases, the CDU understanding of democracy is maximally representative which I think breeds antidemocratic sentiment. I.e. they want people to vote every four years but that is all they expect voters to decide, and they don’t want to be transparent toward voters.
