The terms used in subdivisions (i), (ii), and (iii) of this subparagraph shall have the meanings provided in paragraph (c)(3) of this section. An organization's articles will not violate the provisions of paragraph (b)(3)(i) of this section even though the organization's articles expressly empower it to make the election provided for in section 501(h) with respect to influencing legislation and, only if it so elects, to make lobbying or grass roots expenditures that do not normally exceed the ceiling amounts prescribed by section 501(h)(2) (B) and (D).
The term legislation, as used in this subdivision, includes action by the Congress, by any State legislature, by any local council or similar governing body, or by the public in a referendum, initiative, constitutional amendment, or similar procedure. An organization will not fail to meet the operational test merely because it advocates, as an insubstantial part of its activities, the adoption or rejection of legislation. An organization for which the expenditure test election of section 501(h) is in effect for a taxable year will not be considered an action organization by reason of this paragraph (c)(3)(ii) for that year if it is not denied exemption from taxation under section 501(a) by reason of section 501(h).
The term candidate for public office means an individual who offers himself, or is proposed by others, as a contestant for an elective public office, whether such office be national, State, or local. Activities which constitute participation or intervention in a political campaign on behalf of or in opposition to a candidate include, but are not limited to, the publication or distribution of written or printed statements or the making of oral statements on behalf of or in opposition to such a candidate.
An organization may be educational even though it advocates a particular position or viewpoint so long as it presents a sufficiently full and fair exposition of the pertinent facts as to permit an individual or the public to form an independent opinion or conclusion. On the other hand, an organization is not educational if its principal function is the mere presentation of unsupported opinion.
