Republican-only votes are like counting only the votes of those who voted for your favorite candidate.
No, you don't get it.
This is a Republican primary. Counting Republican-only votes in a Republican primary, when ones logical point is specifically about Republican voters is NOT the same as your nonsequitur example.
As I said, Republicans are freaking out, because McCain hasn't won one primary or caucus amongst "Republican only" voters.
In other words, you remain in deep denial. Go to Tradesports and sell McCain nomination futures short. Don't bet your house, though.
