Saturday 5 March 2016 (presumably): All 46 of Kentucky's delegates to the Republican National Convention are bound to presidential contenders based on the results of the voting in today's Kentucky Presidential Caucuses.

• 46 delegates to the National Convention are to be allocated proportionally among those candidates receiving 5% or more of the statewide caucus vote.
• The proportional delegate allocation shall be rounded to the nearest whole delegate. In the event that a delegate is unallocated due to mathematical rounding, the unallocated delegate vote shall be cast in favor of the candidate closest to the rounding threshold. In the event that delegates are over-allocated due to mathematical rounding, the over-allocated delegate shall be removed from the candidate furthest from the rounding threshold.

On 9 February 2015, Senator Rand Paul (Republican, Kentucky) asked the Republican Party of Kentucky to hold a Presidential Caucus prior to the May partisan and Presidential primary election. Kentucky does not allow a candidate to appear on the ballot twice and Senator Paul may want to run for President and for re-election in the May primary.

Name of candidate to appear on ballot but once ... No candidate's name shall appear on any voting machine or absentee ballot more than once, except that a candidate's name may appear twice if he is a candidate for a primary or a regular election and also a candidate to fill a vacancy in the same office required .... [Kentucky Revised Statutes 118.405]

7 March 2015: The Republican Party of Kentucky Executive Committee voted unanimously by voice vote to nominate their national convention delegates by Presidential Caucus in 2016. Changing to a caucus would let Rand Paul run for re-election to the U.S. Senate in the Primary and President in the caucus. Such caucuses would be held in March.

... In the year in which the President of the United States shall be elected, all precincts shall hold elections for Party office not earlier than March 1 and not later than March 31. ... [OFFICIAL RULES OF THE REPUBLICAN PARTY OF KENTUCKY ... SEPTEMBER 17, 2011 - 5.03 (a)]

The State Central Committee will meet on 22 August 2015 to formally vote on the proposal.
