Dan S Sullivan, the Republican senator, will be joined on the November ballot in Alaska by a challenger with a nearly identical name from the same party, election officials confirmed on Tuesday, adding a twist to what is expected to be one of the most hotly contested races of the midterms.
The Republican senator is running for a third term against Democrat Mary Peltola, a former US House representative whom polls show is neck-and-neck with him in a state that hasn’t sent a Democrat to the Senate since 2008.
