12 MCCUTCHEON v. FEDERAL ELECTION COMM’N Opinion of ROBERTS, C. J. a donor’s contributions to a political committee are now limited, a donor cannot flood the committee with “huge” amounts of money so that each contribution the committee makes is perceived as a contribution from him. Buckley, supra, at 38. Rather, the donor may contribute only $5,000 to the committee, which hardly raises the specter of abuse that concerned the Court in Buckley. Limits on contributions to political committees consequently create an additional hurdle for a donor who seeks both to channel a large amount of money to a particular candidate and to ensure that he gets the credit for doing so.

In effect, the rule eliminates a donor’s ability to create and use his own political committees to direct funds in excess of the individual base limits. It thus blocks a straightforward method of achieving the circumvention that was the underlying concern in Buckley.

For example, the regulations construe earmarking to include any designation, “whether direct or indirect, express or implied, oral or written.” 11 CFR §110.6(b)(1). The regulations specify that an individual who has contributed to a
