Why does every long-term Atlas prediction involve a early-to-mid-21st Century Democratic realignment? Before Trump won, the consensus was that it started in 2008, and now they have just shifted the goalposts to 2020/2024. Partisan realignments are becoming more and more rare, and there is no evidence that we are about to embark in a long-term Democratic era. In fact, the author of "The Emerging Democratic Majority" (from the early 2000s) has now recanted and said that we are entering a Republican era.
Because the last realignment was 47 years ago towards the Republicans and maybe it will be 5 years or maybe 50 years from now, but it will happen as long as the United States doesn't break up or becomes a kingdom before realignment takes place
I would argue that our last realignment was in 1992 as right now we are neither in dem dominance or GOP domaine
