Illinois Code § 7-10.3

§ 7-10.3.

(A) Except as otherwise provided in paragraph (C) of this Section, a candidate for delegate or alternate delegate to a national nominating convention shall file with the State Board of Elections at the time of filing the statement of candidacy described in Section 7-10, a statement declaring the name of his preference for President of the United States or that he is uncommitted. (B) If more candidates for delegate or alternate delegate in a congressional district than have been allocated to that district file statements designating the same presidential candidate as their preference for President of the United States, the presidential candidate so designated or his authorized representative may, within 10 days after the last day for filing such statements, file an affidavit designating which of such candidates he wants to be listed on the ballot as being committed to the presidential candidate. Candidates for delegate or alternate delegate not designated on an affidavit by the presidential candidate shall be listed on the ballot as uncommitted. In no event may the designated person's filing of the affidavit leave fewer candidates listed on the ballot as being committed to him than the number of delegates or alternate delegates allocated to the district. (C) The State central committee of a political party may choose to file a statement with the State Board of Elections not less than 30 days prior to the first day for filing the statement of candidacy described in Section 7-10, specifying that a candidate for delegate or alternate delegate shall not be required to file an official declaration statement pursuant to this Section. If the State central committee of a political party specifies that any such official declaration statement is not required to be filed by the candidates for delegates and alternate delegates to the national nominating convention of any such political party, then no such declaration statement shall be required to be made.
