In politics, what is the horseshoe theory?

The horseshoe theory postulates that the far right and far left are not at opposite ends but rather are closer together like the ends of a horseshoe with the center being at the curved part of the shoe. The theory name is attributed to Jean-Pierre Faye of France in his book "The Century of Ideologies". Scholars are primarily skeptical of the theory and suggest that it may only apply in very specific conditions.
