Correction. Mr. Goldberg's fine book is called "Liberal Fascism." Sorry for the mistake.
Mr. David Horowitz, now a staunch conservative, but once was a radical Marxist himself, writes a number of wonderfully informative booklets exposing the Lefts lies and radical plans. His booklet "Barack Obama's Rules For Revolution-The Alinsky Model is short , but very informative.
I believe these booklets can be obtained by contacting him at FRONTPAGEMAG.COM, NEWSREALBLOG.COM, or at DISCOVERTHENETWORKS.ORG A Guide To The Political Left. Spread the word with the written word.
