New York Post. WHAT exactly does a "community organizer" do? Barack Obama's rise has left many Americans asking themselves that question. Here's a big part of the answer: Community organizers intimidate banks into making high-risk loans to customers with poor credit.

In the name of fairness to minorities, community organizers occupy private offices, chant inside bank lobbies, and confront executives at their homes - and thereby force financial institutions to direct hundreds of millions of dollars in mortgages to low-credit customers.

In other words, community organizers help to undermine the US economy by pushing the banking system into a sinkhole of bad loans. And Obama has spent years training and funding the organizers who do it.

THE seeds of today's financial meltdown lie in the Community Reinvestment Act - a law passed in 1977 and made riskier by unwise amendments and regulatory rulings in later decades.

CRA was meant to encourage banks to make loans to high-risk borrowers, often minorities living in unstable neighborhoods. That has provided an opening to radical groups like ACORN (the Association of Community Organizations for Reform Now) to abuse the law by forcing banks to make hundreds of millions of dollars in "subprime" loans to often uncreditworthy poor and minority customers.

Any bank that wants to expand or merge with another has to show it has complied with CRA - and approval can be held up by complaints filed by groups like ACORN.

In fact, intimidation tactics, public charges of racism and threats to use CRA to block business expansion have enabled ACORN to extract hundreds of millions of dollars in loans and contributions from America's financial institutions.

Banks already overexposed by these shaky loans were pushed still further in the wrong direction when government-sponsored Fannie Mae and Freddie Mac began buying up their bad loans and offering them for sale on world markets.

Fannie and Freddie acted in response to Clinton administration pressure to boost homeownership rates among minorities and the poor. However compassionate the motive, the result of this systematic disregard for normal credit standards has been financial disaster. Read it all.
