Well if NZ swings right it could be part of larger trend where progressive leaders be it Sanna Marin, maybe Pedro Sanchez (but today's election inconclusive), and Ardern who are were all seen as examples progressives looked up to. Yes you still have Macron and Trudeau although Macron pretty centrist so as was case when Trump won in 2016, it once might again fall to Trudeau is the champion for progressive policies in West.
Why would Macron or Trudeau come to your mind when you think of progressives?
