I'd say closer to 90-100. At least since the New Deal, but probably since the times leading up to it. The America First movement in the lead up to WW2 who thought we should side with the Nazis is indistinguishable from the America First movement today, which is comprised of Nazis.
It's a sombering thought that Germans were not all nazis, their government was. Right now USA has a lot of (semi)closet nazis both in economic and political positions of power.
