JUNEAU -

Alaska Libertarians have a new U.S. Senate candidate.

The Division of Elections director says Mark Fish will be the Alaska Libertarian party candidate after Thom Walker withdrew. Tuesday was the deadline for political parties to swap-out candidates.

Fish received the party's endorsement ahead of last month's primary, but Walker, an unknown recently registered as a Libertarian, won. Party chairman Michael Chambers has said voters might have confused Thom Walker with Bill Walker, an independent candidate running for governor.

At least five candidates are set to appear on November ballot for the Senate seat held by Democrat Mark Begich, who's seeking re-election.

Fish rejects suggestions he could be a spoiler in a tight race between Begich and Republican Dan Sullivan, saying Libertarians have a right to voice their opinions and positions.
