First-term Democratic Senator Mark Begich is trying to hold off Republican Dan Sullivan, a former state attorney general, in Alaska. Begich has touted his deep roots in the state, where his father was a congressman, and painted Sullivan, born in Ohio, as an outsider.
Republicans are expected to pick up seats in the U.S. Senate, but polls show eight to 10 races are still toss-ups and it is unclear whether they can gain the six seats they need to control the 100-member chamber for the first time since the 2006 election.
