Anchorage Mayor Dan Sullivan has filed a letter of intent to run for state office, but he says he's still keeping his options open about what he might run for, and he might not run for any.
Sullivan notified the Alaska Public Offices Commission of his intent, but so far he has not registered with the Federal Election Commission for any federal office.
Democratic Senator Mark Begich comes up for re-election next year, as well as Republican Representative Don Young.
