The Republicans have a new meme: Obama is Marxist. Never mind that almost nobody can tell anyone what a Marxist is--Karl or Groucho. Obama's now an elite Marxist (!!).
I have a new meme too: McCain is fascist. There are plenty of speeches and articles written by him that call for massive mobilization in time of war. According to noted right-wing intellectual Jonah Goldberg, Woodrow Wilson was our first fascist president because he mobilized the entire nation for a common purpose. (It works if you re-define "fascist," "common," and "entire." And are very vague about "purpose.")
Therefore McCain is fascist, and since Hitler was fascist, McCain is Hitler.
Q. E. D.
Goldberg said some other stupid things too but I don't have all day.
