At one time Wikipedia had a big section on this, but no longer. Here is a summary taken principally from a USA Today article according to the citation,

Hypocrite
Buchanan calls himself an outsider, which is ridiculous. When not running for president, he makes $1 million a year as part of the “liberal media”, and he has worked in the White House for 3 presidents.

Buchanan is a big hypocrite. Though he attacks big corporations like AT&T and General Electric for laying off Americans and investing overseas, he gets a piece of their profits from the stock he owns — between $15,000 and $50,000 each in AT&T, DuPont, General Motors and General Electric. Pat owns between $50,000 and $100,000 in IBM stock as well. His multi-million portfolio also includes interests in a British bank, YPF Sociedad Anonima (an Argentine oil company), and China Light and Power, a Hong Kong utility that owns part of a Chinese power plant.

Buchanan attacks immigrants and foreigners, but his housekeeper is South American …

He likes to brag that his biggest campaign contributor — Roger Milliken, a textile billionaire — gave him just $60,000. But Milliken also secretly gave $1.7 million to The American Cause, Buchanan’s protectionist group, and to an affiliated lobbying arm. And Milliken directly paid for “99 percent” of the anti-GATT ads Buchanan ran in 1994, according to a Buchanan accountant quoted in Newsweek.

Sheltered Washington Insider:

Pat has always led a very sheltered upper class life, and has never worked for anyone except the federal government and the media — while attacking both the whole time. In fact, he lived off the federal payroll even as a kid — his dad was a government accountant and then managing partner of Councilor, Buchanan & Mitchell, one of the largest accounting firms in the Washington D.C. area. He earned enough to raise several kids in an affluent neighborhood, with enough left over to buy a Cadillac. Even George Bush was less sheltered than Buchanan — he at least lived in Texas and China, and worked in the private sector …

He has never lived or worked outside of the Washington “beltway” cocoon, except a 3 year stint as an editorial writer for a now-defunct conservative paper in St. Louis.

Buchanan’s sheltered life explains why it took him until 1992 to discover that working men were losing jobs, and their wages were falling. That’s why he didn’t notice his own hypocrisy of preaching “America First” while driving a Mercedes in the 1992 election. (Worse yet, he tried to blame it on his wife.)

I assume realchange.org is partisan, but what they say is correct.
