Step-by-step explanation:

Since no one got more than 50% of the total votes, there are no automatic winners.  Last place is eliminated, and those votes go to whoever those voters chose for their next favorite.  This keeps repeating until there's only one candidate left.

The table shows the counts for the voters' first place choice.

Gonzalez has the least votes, so he is automatically eliminated.  Those votes then go to the voters' second choice.  We don't know what that is, so let's assume they all go to Macpherson.  Macpherson would then have 21 + 54 = 75 votes.  But that would still be less than Ndelo, so Macpherson is also eliminated.

Now let's assume that the Gonzalez and Macpherson votes all go to Ndelo.  Ndelo would now have 21 + 54 + 83 = 158 votes, barely beating Walsh.

Therefore, everyone from Ndelo and up has a chance of winning.
