We fully characterize in a mass election model the set of candidates that can win with positive probability in equilibrium when the voters are allowed to vote for as many candidates as they want. If at most two candidates can win for some undominated strategy profile (“in the race” candidates), we predict that the unique equilibrium outcome is the victory of the Condorcet Winner. For any election with more candidates “in the race”, we show that all the candidates “in the race” can be tied for victory.
