Liberalism and progressives are two different animals
John F. Kennedy would run a mile from the Progressives, he was more of a Classical Liberal.
Again, there's no such thing. "Classical Liberal" is a bullshit term used by latter-day revisionists as an excuse to misapply the term "Liberal". And then "Progressivism" was a movement a century ago, and included both Democrats and Republicans in pretty much equal numbers.
