Not such a bad a result. In many states Sullivan and Miller would be now campaigning for a runoff vote. And I think Miller has lost some appeal after he lost to Murkowski when she was a write-in candidate.

Miller lost by 8 points despite the usual triangulation tactics that split conservatives, and despite the fact that he had no media and no money. If he got any support at all he would have won. Sad.
