Political Action Committees (PACs) spent a record $416 million in the 2008 federal elections -- most on candidates for the House and Senate.
As one who once ran the multi-million dollar PAC for the National Association of Realtors -- at the time the largest in the nation -- I can say as an absolute fact that those who sign the checks don't do so without expecting something in return.
PAC contributions fall into two categories -- payment for services received or an investment for services that special interest group expects to receive.
In 1988, as the Vice President for Political Programs for the Realtors, I debated Republican Congressman Guy Vander Jagt -- at the time the chairman of the National Republican Congressional Committee (NRCC) on National Public Radio.
"PACs," Vander Jagt said, "are nothing but whores."
