Normally I'd say the state committee would probably just appoint Santorum delegates in districts he won, but with the complete lack of respect for democracy and their members' own votes the GOP always shows I wouldn't put it past them at all to just appoint a slate of Romney supporters (though probably officially "uncommitted")
Romney would never accept delegates that he did not win legitimately.

Those
were okay, under the party rules.
This is a bit different. I'm not sure if the candidate that wins the district wins the delegate; in PA, they do not.
