Illinois is a “Direct Election primary”.

Here is a link to the status of all the states as well as the counts; http://www.realclearpolitics.com/epolls/2012/president/republican_delegate_count.html

That's not quite how it works. You are confusing raw polling data with Delegate allocations. You are not even close to how it works. Santorum needs over 70% after today, and Romney will also get 150 Super Delegates. Ron Paul will also probably hand his delegates over to Romney as well.

IL is winner-take-all by district in the form of a direct delegate election. Mitt's, Newt's, Rick's and Paul's delegates are all shown on the ballot by name. Whichever 3 or 4 per district get the most votes are the winners. So if this poll holds and Mitt's delegates win 41% of the vote in a district, they win 100% of the delegates with 41% of the vote. He could sweep the state if that poll holds in every district. But as people have said here some districts are more heavily liberal and some more conservative, so it remains to be seen what districts will end up being "could've, would've, should've" districts where the combined Newt and Rick vote could have switched Romney from being the winner to the loser.

About 800 of the 1200 remaining delegates are in winner-take-all states or districts, or ones that become winner-take-all if a candidate hits a percentage threshold of the vote.

Illinois (direct delegate election by district)

There’s another interesting way you can vote in Illinois. You can select Newt as your presidential choice, but vote for Santorum’s delegates. The presidential pick is nothing but a straw poll that’s non-binding. The delegates you pick are what counts. If it’s true that Santorum didn’t get delegates on every district ballot, then you may also want to vote for Newt’s delegates as a substitute. You could even go nuts and vote for one Newt, one Rick, one Mitt and one Paul delegate on your ballot. A good option for the undecided voter. ;)
