Sasuke has too many fangirls not to be prom king. Asuma would have been prom king on the strength of his name and connections alone.
Ino is both popular and a clan heir, which gives her the edge over Sakura for Queen. If Asuma is King, Kurenai is Queen.
I doubt Neji is liked enough by his peers to be King.
