U.S. Sen. Lisa Murkowski is returning to Alaska to address supporters after increasing her lead over GOP rival Joe Miller.
Murkowski holds a 10,400-vote advantage with only an estimated few hundred uncounted ballots remaining. She plans to address supporters in her home state Wednesday after the last ballots are tabulated.
Murkowski is seeking to make history as the first U.S. Senate candidate to win as a write-in since 1954.
Miller, the Republican nominee, has returned home to Fairbanks after spending time this week in Anchorage, where he met with his legal team.
Murkowski's widening lead has put pressure on Miller to decide whether to press forward with a federal lawsuit challenging election procedure, demand a recount or concede.
