(a) For each district from which an officer of the federal or state government is elected, a district executive committee is established as provided by this subchapter for each political party holding a primary election.
(b) The state executive committee may by rule require a specific deadline for filling vacancies on a district executive committee before that committee fills a vacancy in nomination for public office, but may not set the deadline for a date later than the date that the vacancy in nomination for public office occurred. The deadline does not apply to the filling of a vacancy if the executive committee contains no members.
