Well, there's the McCain-Feingold Campaign Finance Reform Act:
SEC. 313. USE OF CONTRIBUTED AMOUNTS FOR CERTAIN PURPOSES.
(a) PERMITTED USES-
(b) PROHIBITED USE-
(1) IN GENERAL- A contribution or donation described in subsection (a) shall not be converted by any person to personal use.
(2) CONVERSION- For the purposes of paragraph (1), a contribution or donation shall be considered to be converted to personal use if the contribution or amount is used to fulfill any commitment, obligation, or expense of a person that would exist irrespective of the candidate's election campaign or individual's duties as a holder of Federal office, including--
(A) a home mortgage, rent, or utility payment;
(B) a clothing purchase;
(C) a noncampaign-related automobile expense;
(D) a country club membership;
(E) a vacation or other noncampaign-related trip;
(F) a household food item;
(G) a tuition payment;
(H) admission to a sporting event, concert, theater, or other form of entertainment not associated with an election campaign; and
(I) dues, fees, and other payments to a health club or recreational facility.
So buying clothing is deemed a conversion for personal use and prohibited. It doesn't matter that Palin's giving it all to charity after this is over.
But wait, it's the RNC spending the money, not the McCain/Palin campaign!
'(a) NATIONAL COMMITTEES-
'(1) IN GENERAL- A national committee of a political party (including a national congressional campaign committee of a political party) may not solicit, receive, or direct to another person a contribution, donation, or transfer of funds or any other thing of value, or spend any funds, that are not subject to the limitations, prohibitions, and reporting requirements of this Act.
'(2) APPLICABILITY- The prohibition established by paragraph (1) applies to any such national committee, any officer or agent acting on behalf of such a national committee, and any entity that is directly or indirectly established, financed, maintained, or controlled by such a national committee.
Nope, they're subject too.
So the RNC and the McCain/Palin campaign are violating the McCain-Feingold Campaign Finance Reform Act? The same act that McCain uses to shore up his flagging "maverick" status? Sure looks like it.
