He was a member of the
New York State Senate (26th D.) from 1872 to 1875, sitting in the
95th,
96th,
97th and
98th New York State Legislatures. He was elected to the
New York State Senate in the fall of 1871, as a Democrat representing the 26th District, then comprising
Ontario, Seneca, and
Yates counties. He was elected with a vote majority cited between 950 and 1500 in a primarily
Republican district. He became a member of the standing committees on Canals, Manufactures, and Grievances. During this first senate term, then-State Senator
William M. Tweed was embroiled in his corruption and
embezzlement scandal. As Chairman of the Special Committee investigating Tweed in the State Senate, Johnson went to meet with Tweed, who declared himself too sick to speak with the Senator. Being charged with only 30 days in which to act on the matter, Johnson used what he viewed as Republican attempts at interference as leverage to aid in the passage of his bill for the creation of an investigatory panel. "Boss Tweed" was convicted in 1873. Johnson was re-elected to the State Senate by a margin of less than 200 votes. During his second term as a State Senator, he was a member of the committees on Canals, Manufactures, and Militia. On October 11, 1875, Johnson returned to Seneca Falls after having been in New York City. He fell ill that afternoon and died hours later of unreported causes. ==Personality==
