How this is done is usually by multiple tiggers. First on initialization set a variable to the total number of players in the game. Then another trigger with the event of button clicked/checked set or rather modify another variable ( or array with each option), hide the button, then check and modify the count of players left to vote. If it returns 0 run the game level. I would just use a nested if then to compare which array variable is largest.
