In reading the RNC rules, I wonder if it’s the state party that can change their rules to be in compliance with RNC Rule 16? so no primary, let the state republican committee select the delegates and alternates ? ( some of this stuff makes my head spin )
from the RNC Rule 16:
(c) Timing and Allocation.
(1) No primary, caucus, convention, or other process to elect, select, allocate, or
bind delegates to the national convention shall occur prior to March 1, nor shall any such process occur after the second Saturday in June in the year in which a national convention is held or less than forty-five (45) days before the national convention is scheduled to
begin.
(d) General.
In all elections or selections of delegates or alternate delegates to the national convention, the following rules shall apply:
(1) Delegates and alternate delegates to the national convention may be elected,
selected, allocated, or bound only in one of the following manners:
(i) by primary election;
(ii) by the Republican state committee;
(iii) by state and/or congressional district conventions;
(iv) by any method consistent with these rules by which delegates and alternate delegates were elected, selected, allocated, or bound to the most recent Republican National Convention from that state; or
(v) by Rule No.14(a)(2) of these rules.
(2) In electing or selecting delegates and alternate delegates to the national convention, no state law shall be observed which hinders, abridges, or denies to any citizen of the United States, eligible under the Constitution of the United States to hold the office of President of the United States or Vice President of the United States, the right or privilege of being a candidate under such state law for the nomination for President of the United States or Vice President of the United States or which authorizes the election or selection of a number of delegates or alternate delegates from any state to the national convention different from that fixed in these rules.
