Republican Senate hopeful Joe Miller of Alaska says incumbent Sen. Lisa Murkowski's "little victory speech" may have been premature.
Miller said he's not ready to concede defeat in the closely watch contest.
Miller, a tea party favorite endorsed by Sarah Palin, defeated Murkowski in the GOP primary. Then Murkowski launched an unlikely write-in campaign to hold onto her Senate seat.
Initial returns show write-in ballots hold an edge of more than 13,000 votes over Miller. But it isn't yet clear how many of the write-in votes are for Murkowski.
Since election night, Murkowski has sounded confident of victory. She told supporters her write-in campaign "will change the definition of American politics."
