Ted Stevens won the Alaska primary with over 60% of the vote.
Interestingly though, Don Young and Sean Parnell both got 45% of the vote. In actual votes, Don Young received 42,461 votes and Sean Parnell received 42,316 votes.
I'm not sure if Alaska has runoffs. My understanding of the news reports this morning is that Alaska does not. Likewise, there are still votes being counted.
