Cognoscent Radical

As Trotsky said, in moments of crisis, people with no politics tend to develop the worst possible politics. This is from Ann Coulter, an obvious cognoscenta of all things radical.  Should I  be ashamed to quote....? Am I quoting Trotsky or Coulter. Is she a cognoscente or cognoscenta?  The comedy of  permanent revulsion. 
But the observation is right. (although coming from the left)
