In my view the right has not moved but the left has moved so far left that the middle is no longer palatable to most Americans. And we know despite the recent elections the left isn't going to look inward to their mistakes and correct them . Look at who continues to head their party. You speak of America First but the left desires globalization meaning a new world order, ergo open borders and their social justice agenda, push for neutral gender, anti-cop anti-religion, anti-capitalism, etc

I opine others can decide
