Alaska Republican U.S. Sen. Dan Sullivan

A man named Dan Sullivan, same as Alaska's Republican U.S. Senator Dan Sullivan, sued to remain on the August primary ballot after being disqualified by state elections officials. The challenger claims his disqualification violates state and federal law, while officials argue his candidacy was filed to confuse voters. The National Republican Senatorial Committee and the senator himself called the challenger a 'sham candidate' but did not provide evidence of coordination with Democratic candidate Mary Peltola, whom the challenger denies.
