From January to April, voter registration increased faster for independents in South Dakota than for Republicans and Democrats combined. The numbers as of April 6 compiled by the state elections office show:
Republicans grew by about 1,100 to 242,163;
Democrats declined by more than 200 to 175,514;
Independents rose by more than 1,900 to 105,784;
Constitutionalists increased by 6 to 582;
Libertarians increased by 41 to 1,443; and
Americans Elect added 2, rising to 12.
In other words, more voters chose to be independent than to be Republican (or any other party). And more voters chose third-party affiliations than to be Democrats.
