The term refers to the "horseshoe theory" of politics, which holds that on the extremes the far left and far right are very similar.
"What do the radical right and the radical left have in common? The so-called horseshoe theory, attributed to the French writer Jean-Pierre Faye, argues that the ends of the political spectrum are much more similar than one might expect at first sight. According to this theory, the political continuum from left to right is not a straight line, but takes the shape of a horseshoe." https://ecpr.eu/Events/Event/PanelDetails/3246
