I don't think there is an option to do what you are asking (that I am aware of).
My only thought is that you could let people type it out (ensuring there is a comment to say they need to spell the name correctly), and then export the results to Excel, sort the nominee column to group the same names together, and then you can do a count to tally things up.
As a side benefit, once the data is in Excel, you could do some cool things such as a pie chart of the % of how each nominee did.
Might make a good speal when you are presenting? E.g. With 23% of the vote, Oliver Queen hold a year quarter of the competition.
Anyway just my two cents. Hope it was helpful!
