(AP) – Kansas promises its citizens that it will hold a presidential primary every four years, only to falter before the vote arrives.

Kansas continues to rely on caucuses to declare its preferences for Democratic and Republican presidential candidates. Some officials acknowledge that far more voters would participate in a primary, giving perhaps a truer picture of the state’s views. But they shy away from holding primaries because of their potential cost.

Yet, governors and legislators won’t repeal the law that calls for a primary. The result is that Kansas has held presidential primaries only in 1980 and 1992 and won’t have another until at least 2016.

Kansas Republicans have set presidential caucuses for March 10 and the Democrats, for April 14.
