 Blaine's career as a Republican newspaperman led naturally to involvement in Republican party politics. In 1856, he was selected as a delegate to the first Republican National Convention. From the party's early days, Blaine identified with the conservative wing, supporting Supreme Court Justice John McLean for the presidential nomination over the more radical John C. Frémont, the eventual nominee. The following year, Blaine was offered the editorship of the Portland Daily Advertiser, which he accepted, selling his interest in the Journal soon thereafter. He still maintained his home in Augusta, however, with his growing family. Although Blaine's first son, Stanwood, died in infancy, he and Harriet had two more sons soon afterward: Walker, in 1855, and Emmons, in 1857. They would have four more children in years to come: Alice, James, Margaret, and Harriet. It was around this time that Blaine left the Presbyterian church of his childhood and joined his wife's denomination, becoming a member of the South Parish Congregational Church in Augusta.
