In 1958, Stratton was elected to the U.S. Congress. He rose through seniority to become the third-ranking Democrat on the
Armed Services Committee; though he lost a race for chairman of the committee to
Les Aspin in 1985, he chaired subcommittees including the one on Procurement and Military Nuclear Systems, and was recognized as an expert on defense issues. Stratton consistently succeeded at winning reelection by appealing to
conservative voters and supporting
defense spending in his district, which included
General Electric manufacturing plants and the
Watervliet Arsenal. For his first two terms, Stratton represented a relatively compact district centered around Schenectady. In the early 1960s, the Republican-controlled legislature tried to defeat him through unfavorable redistricting. Stratton's home in
Amsterdam was drawn into a district that snaked from the
Capital District suburbs all the way west across
Upstate as far as
Auburn, including along the way some of the most rural and conservative territory in central New York. On paper, this district seemed unwinnable for a Democrat, even a conservative Democrat like Stratton. However, Stratton was
reelected in 1962 with 54 percent of the vote. He quickly became popular with the voters in this mostly rural district, and went on to win another four terms by well over 60 percent of the vote. The state legislature gave up in the 1970s round of redistricting, and placed Stratton's home into a heavily Democratic seat including the heart of the Capital District. He easily defeated Republican incumbent
Daniel Button, and was reelected seven more times without serious difficulty until retiring in 1989 at the age of 72. In 1962, Stratton was a candidate for
Governor of New York;
Robert M. Morgenthau won the Democratic nomination, but lost
the general election to incumbent
Nelson A. Rockefeller. Stratton was a candidate for the Democratic nomination for the
United States Senate in 1964, hoping to challenge incumbent
Kenneth Keating, but he was defeated by
Robert F. Kennedy, who went on to
win the election. He was a proponent of the
Equal Rights Amendment, and also introduced successful legislation, as a rider to the 1975 defense appropriations bill, which mandated the admission of women to the service academies. In 1976, Stratton led an unsuccessful effort to cite journalist
Daniel Schorr for
Contempt of Congress after Schorr refused to identify his source for a copy of the
Pike Committee report on the clandestine activities of the
Central Intelligence Agency. Schorr had provided the report to
The Village Voice, which made its contents public. ==Retirement ==
