I don't think its really word games when talking about progressivism today. Trump could claim the banner of progressive in the sense that he's trying to progress towards a future he believes is better for all of us, while Democrats are attempting to conserve what they built. Personally I see that as a bullshit word game, but that doesn't mean the words are actually used improperly there.

If someone tells you they are progressive, what is the end goal you expect they mean? Its totally possible that banner is shorthand for a specific goal or direction and I just completely missed the boat there.
