The NYTs details McCains efforts to avoid spending limits. Here's an example from the article,
This month, the McCain campaign began running banner Web advertisements asking for donations to the McCain-Palin Compliance Fund, a fund-raising vehicle rooted in a 1980s F.E.C. ruling that candidates who accept public financing can still collect private donations for legal and accounting costs for complying with campaign finance laws.
Only a careful observer, however, would have noticed the advertisements’ fine print, which said donations to the fund would be used to pay for “a portion of the cost of broadcast advertising,” as well as other expenses.
That would seem to be a far cry from the legal and accounting exemption.
