NEW YORK – New Zealander Trevor Loudon has just published an encyclopedic new 689-page volume, “The Enemies Within: Communists, Socialists and Progressives in the U.S. Congress,” to accompany his 668-page 2011 book, “Barack Obama and the Enemies Within.”

In both volumes, Loudon has proved himself to be among the foremost experts in the world investigating and reporting the penetration of communists, socialists and the current group of “progressives” affiliated with Democratic Party politics who portray themselves as liberals.

In his 2011 book, Loudon presented documented evidence that Barack Obama’s rise in politics was not an accident, but a conscious, decade-long effort by the radical left to promote a candidate with African roots. Obama, he said, was packaged as an engaging and seemingly harmless Trojan Horse radical, sent to Chicago to refine his skills running for office as a Democratic Party politician.

It is impossible to read “Barack Obama and the Enemies Within” without being convinced that Obama’s education in communist ideology stretches from the extracurricular education he received from Communist Party mentor Frank Marshall Davis in Honolulu to his recruitment as a New Party candidate in Chicago, with strong ties to the Democratic Socialists of America.

Loudon continues naming names in his current volume, “The Enemies Within,” which documents how extensively communists, socialists and progressives have penetrated the U.S. Congress, running on the Democratic Party ticket.

The goal of these radicals in Congress, Loudon demonstrates, is the same goal Obama announced when running for president in 2008, to transform the United States from the constitutional republic established by its Founding Fathers into a radical socialist state. The aim is to be achieved through passing extensive social welfare legislation designed to bankrupt a government adhering to concepts of private property and private enterprise.

In an insightful essay on the Democratic Socialists of America, Loudon emphasizes the impact on U.S. radicals of the late Italian Communist Party theoretician Antonio Gramsci, whose writings from prison declared that the “working class revolution” is a dead end, arguing instead that communism can best be achieved “by infiltrating civil society – political parties, churches, labor unions, universities, the media, community groups, etc., to turn them into revolutionary vehicles.”

Similarly, Loudon documents how the Communist Party of the USA itself has adopted a stealth plan to achieve revolutionary goals by decisions made in the 1970s to infiltrate and manipulate the Democratic Party. The plan is to form alliances with the radical elements in organized labor in conjunction with radicals in the African-American community and the feminist movement to establish a progressive coalition on the left that could dominate the national political agenda for decades to come.

His essay on the Institute for Policy Studies provides extensive evidence that the IPS, operating today with the distinction of being oldest – founded in 1963 – and most influential of the far left “think tanks” in Washington, D.C., “works closely with several U.S. Marxist groups, but is particularly close to the Democratic Socialists of America.”

The congressional profiles of current members of Congress provides extensive evidence of radical leftist ties in the backgrounds of top Democratic Party legislators, including Democratic Party Sens. Barbara Boxer, Dick Durbin, Tom Harkin, Barbara Mikulski, Elizabeth Warren, Ed Markey, Debbie Stabenow, Al Franken, Sherrod Brown, Ron Wyden, Jeff Merkley, Patty Murray and Tammy Baldwin.

In the House of Representatives, Loudon profiles the radical left background of Democratic Party Reps. Nancy Pelosi, Louis Gutierrez, John Conyers, Charles Rangel, Marcy Kaptur, Peter DeFazio, Sheila Jackson Lee, Jim McDermott and dozens more.

Loudon’s profiles of the radical lawmakers is extensively footnoted, complete with photos, news clips, website screen captures and quotations from published sources that leave no doubt as to the authenticity and accuracy of his allegations.

In documenting the success with which the radical left has captured the politically correct core of Democratic Party politics since the 1970s and the end of the Vietnam War, Loudon joins bestselling author Paul Kengor, who published in 2010 “Dupes: How America’s Adversaries Have Manipulated Conservatives for a Century,” followed in 2012 by “The Communist: Frank Marshall Davis, The Untold Story of Barack Obama’s Mentor.”

What authors Loudon and Kengor show is that communism in America did not die with the fall of the Berlin Wall. It is alive and well, with ties that run deep today with Barack Obama in the White House and the radical leftist Democrats serving in the halls of Congress.

Loudon will be in Washington, D.C., at the National Press Club Aug. 20 to participate in the all day conference “The Crisis in American Journalism and the Conservative Response,” hosted by the public policy group America’s Survival Inc.

Joining Loudon, who is listed on the program to speak about his book “The Enemies Within,” will be Kengor, presenting his new book, “All the Dupes Fit to Print: Journalists Who Have Served as Tools of Communist Propaganda.”
