Miscellaneous advertisements.

Any advertisement, other than a political advertisement, independent expenditure, or electioneering communication, on billboards, bumper stickers, radio, or television, or in a newspaper, a magazine, or a periodical, intended to influence public policy or the vote of a public official, shall clearly designate the sponsor of such advertisement by including a clearly readable statement of sponsorship. If the advertisement is broadcast on television, the advertisement shall also contain a verbal statement of sponsorship. This section does not apply to an editorial endorsement. For purposes of this chapter, an expenditure made for, or in furtherance of, a miscellaneous advertisement is not considered to be a contribution to or on behalf of a candidate, and does not constitute an independent expenditure. Such expenditures are not subject to the limitations applicable to independent expenditures.
