In 1945, Watkins was elected Sheriff of Delaware County, Pennsylvania and served one term through 1948. In 1948, Watkins was elected to the Pennsylvania State Senate, 9th district, where he served from 1949 to 1960. He was succeeded by Clarence D. Bell. Watkins served one term as county commissioner for Delaware County, from 1960 to 1964. In 1964, Watkins was elected to the 89th United States Congress as a representative for Pennsylvania's 7th congressional district and served from 1965 to 1967. Watkins was reelected to the 90th United States Congress and the 91st United States Congress. Watkins served on the Committee on Interstate and Foreign Commerce during the 89th and 90th Congresses. He was appointed a member on Oct. 19, 1966, upon the resignation of vice Willard S. Curtin. At his death, he was succeeded on the committee on Sept. 23, 1970 by Republican John G. Schmitz of California.
Redistricting controversy
On February 17, 1964, the U.S. Supreme Court rendered a long-awaited decision on congressional redistricting. By a six to three vote, the Court, in Wesberry v. Sanders that "as nearly as practicable, one man's vote in a congressional election it to be worth as much as another's." The effect of this ruling meant that the redistricting in Pennsylvania and many other states based on the 1960 census was nullified and would need to be redone. In regards to his opposition to reapportionment and possible shift his home town of Birmingham and the rest of western Delaware County with Chester County Watkins commented, "It just doesn't seem right to me that a portion of Delaware County should be tacked onto some other county just to reach someone's idea of a magical figure." In January 1966, he testified to that effect before the state Senate reapportionment Committee and said that by 1970, Delaware County would have enough population to support two congressmen. In February, Watkins again attacked the pending redistricting plans:
If it is done now, large portions of Delaware County will be cut off from the balance of the county, attached to either Chester or Montgomery Counties and our people will be virtually without representation in Washington for at least the next four years. It will mean that Montgomery and Chester Counties will control those districts. It will mean that congressmen from those districts will not be working solely for Delaware County municipalities.
With the shift of Watkins' hometown of Birmingham to the new Ninth District, the Seventh District became an open seat, which would be filled that year by Springfield Republican leader Lawrence G. Williams. In the meantime, Watkins now represented a district where 56% of the residents resided in Chester County. In spite of the desire of some leaders that the district be represented by a Chester County resident, an accommodation was reached between the War Board and the leadership of the former, allowing Watkins to continue. He was easily re-elected in November, 1966, beating Democrat Louis F. Waldman, 81,516 to 48,656. Watkins died in West Chester, Pennsylvania from a heart attack during a speaking engagement at the Penn Oaks Country Club. He is interred at Birmingham-Lafayette Cemetery in Birmingham Township, Pennsylvania.
