Earlier this year the Kentucky Republican Party decided to choose delegates to the national convention by caucus, in March, instead of using the May presidential primary. State law gives a party until December 31, 2015, to tell the state that it doesn’t want a presidential primary.
The Kentucky Republican Party still hasn’t filed this notice with state elections officials. It is conceivable that the party wants to wait until the last minute to make the decision final, just in case Senator Rand Paul pulls out of the Republican presidential race. This Politico story says that some Republicans in Kentucky wish he would do that.
