JUNEAU, Alaska – Republican Joe Miller plans to decide Monday whether to continue his legal challenge to Alaska’s U.S. Senate race or stand back and let his GOP rival, Sen. Lisa Murkowski, take office.

This follows the state Supreme Court’s decision Wednesday to uphold election results favoring Murkowski.

Miller told KTVA-TV of Anchorage Wednesday that he expected to decide the next day whether to fight on. But with the holiday weekend approaching, he told Fox News on Thursday that he’d consult with supporters and his legal team and announce a decision Monday.

Monday is the deadline he faces for making any case in federal court.

Miller said all options are being weighed. Those include pursuing constitutional claims in federal court and conceding. He has not publicly indicated whether he is leaning a certain way.

“We’re obviously rational,” Miller told KTVA. “We’re going to make a decision based upon whether or not we think we can continue to do good.”

Miller has argued for a strict reading of the law calling for write-in ballots to have the ballot oval filled in and either the candidate’s last name or name as it appears on the declaration of candidacy written.
