I want to know the answer to the following question:
What is considered a measurement of a state's support to liberal democracy?
All the background I'm provided with is that "Regulation of parties may run from a crackdown on or repression of all opposition parties, a norm for authoritarian governments, to the repression of certain parties which hold or promote ideals which run counter to the general ideology of the state's incumbents (or possess membership by-laws which are legally unenforceable).". Is that enough to answer the question?
Answer: no
