CNN, NBC and Fox News are all calling the Republican primary for John McCain, based on the exit poll and early voting.
That's quite a result for the winner of the 2000 Republican primary in this state. The McCain upset George Bush, the well-funded front runner. This time he's up-ended the wealthy Mitt Romney, as well as seeing off Mike Huckabee and Rudy Giuliani.
At that moment the gap between the two men was nine percentage points, but that could change over the course of the night. [Update: in fact it narrowed to five percentage points with 84% of voting stations reporting.]
McCain's campaign have put out a statement:
We showed the people of this country what a real comeback looks like. We're going to move on to Michigan and South Carolina and victory.
The Republican race remains wide open nationally - who knows who the eventual winner will be?
