Splitting the delegates

So as I ask around today, it seems I am not the only one who was split between Hilary Clinton and Barack Obama. In Illinois, you select the candidate but you also get to elect the delegates. I and other friends (even in other states) dealt with our being torn by splitting the candidates. So many this is why the delegate counts seem so crazy on Real Clear Politics table.  Hilary Clinton has 1012 delegates, while Barack Obama has 933.

In Illinois, Obama won 96 delegate while Clinton won 49. I wonder which part of that was based on percentages and which was based on people splitting the delegates. I'm too tired to do the calculations.

The point is I am still undecided about Clinton and Obama even after the vote.
