Thread:Comments:Rick Santorum sweeps three non-binding GOP presidential contests/What does non-binding mean exactly?/reply

It means the results don't bind any delegates to vote a certain way at the party convention; that determination will be made in each state, as I understand, by a later contest (because if it were made now the state would get only half as many delegates). So Santorum doesn't have any more delegates now than he did before these three contests.
