Primary elections

DENVER — A federal court in Colorado dismissed a suit seeking to block enforcement of a voter-adopted ballot initiative that requires “major political parties to nominate candidates for the general election either through a semi-open primary or, alternatively, through a closed assembly or convection process.” The plaintiffs, five members of the Colorado Republican Party State Central Committee and the People for Association Rights and Bi-Partisan Limited Elections, argued the semi-open primary system violates their constitutional rights and discriminates against major parties.
