<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">propose as a candidate</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for nominate that I've seen before include "Put forward (as candidate for election)" , "Propose for office" , "give name" , "Pick as a candidate" , "Put forward name for a mention" .)
