Assuming that we are talking about the United States, I would say that Progressivism was mostly helpful in allowing the nation to realize its democratic ideals.
The Progressives did a lot of things that promoted democracy. For example, they enacted a constitutional amendment allowing for the direct election of Senators. They also brought in things such as the secret ballot, initiatives and referendums. All of these things allowed for more democracy in terms of elections. Importantly, they also gave women the right to vote.
On the other hand, the Progressives were somewhat anti-democratic on the level of personal rights. The most glaring example of this was Prohibition. The Progressives disapproved of people drinking alcohol (partly because of anti-immigrant sentiment) and more or less made that illegal. By doing so, they took away what is (arguably) a personal right just because they disapproved of that particular activity.
