1. Does it mean that "The reformer succeeds in reestablishing the dark tyranny of the ‘greatest number" with the help of majority votes"?
2. What is the meaning of "must" here. I was taught that must can't make an assumption about the future, as opposed to might/may/could?

2. I don't know who told you that. He is expressing certainty about what will happen in the future.

Those sentences need to trade punctuation. If a sentence could have emotion, I would say the first one would be much happier with a question mark. As for the second sentence, it's probably confused about why it has one.
