Tennessee Code Title 2. Elections § 2-13-314

(a) Delegates-at-large and alternates shall be allocated among the presidential candidates or an uncommitted designation so that the proportion of total delegates committed to any candidate shall equal, as mathematically as is possible, the proportion of the vote received by that candidate.

(b) In no event shall the candidate receiving the greatest number of votes receive fewer district and at-large delegates than the candidate with the next greatest number of votes.

(c) If the total votes received by a presidential candidate in the state at large is less than fifteen percent (15%) of the votes cast, no delegate-at-large or alternates shall be allocated to such candidate and such votes of less than fifteen percent (15%) shall be considered as votes for the uncommitted designation.

(d) Votes for the uncommitted designation shall be considered in the same manner as votes for presidential candidates in the allocation of delegates.
