Early political career

He was a member of the board of supervisors of Bay County for two terms. He returned to Saginaw in 1878 and engaged in the lumber business with his father and also was connected with other business enterprises. He was a member of the East Saginaw common council in 1884 and 1885. He was a member of the Michigan House of Representatives in 1887 and 1888. He was an unsuccessful candidate for Lieutenant Governor of Michigan on the Republican ticket in 1890, losing to Democrat John Strong, Jr. Linton was also president of the Saginaw Water Board and was elected mayor of Saginaw in 1892.

Congress

In 1892, running on the Republican Party ticket in Michigan's 8th congressional district, Linton defeated incumbent Democrat Henry M. Youmans, to be elected to the 53rd United States Congress. Linton was re-elected in 1894 to the 54th Congress, serving from March 4, 1893 to March 3, 1897. He was chairman, Committee on Ventilation and Acoustics in the 54th Congress. In 1896, Linton was defeated in the general election by Democrat Ferdinand Brucker.

In 1895, Linton along with David Swinton, visited Florida looking for opportunity investing in what was then an unsettled frontier. In West Palm Beach, which was the end of the line for the railroad, they headed south by boat. Linton and Swinton liked what they saw, and purchased what is today, much of Delray Beach, and Boynton Beach. They then returned to Michigan to recruit settlers. By the fall of that same year, they had signed up eight settlers. The settlement called Linton was established within a year, having cleared palmetto growth, planting crops, and establishing a post office and store. However, by 1897, Linton had financial trouble and sold some of his holdings to Nathan Smith Boynton to raise some money. By 1898, Linton's creditors moved to collect from Linton's settlers, who had been under the impression that he already had clear title to the land. Some settlers headed back north, and Linton's reputation suffered. Linton returned to Michigan, and the settlement was renamed Delray after Delray, Michigan the hometown of W.W. Blackmer, one of the original eight settlers.^[1]
