In 1964, Vigorito was elected to Congress from a district based in Erie as part of the gigantic Democratic landslide of that year. He was reelected five more times before being defeated in 1976 by Mercer County Solicitor Marc L. Marks.
During his time in office, Nina Totenberg named Vigorito one of the ten dumbest members of Congress.[2]
Later career and death
After his time in Congress, he served on the faculty of Georgetown University in Washington, D.C., from 1977 through 1978. He tried to regain his seat in 1978, but was defeated by Marks.
Vigorito was only the third Democrat to represent the Erie area in the 20th century. Since his loss, one Democrat, Kathy Dahlkemper, represented Erie County for one term from 2009 to 2011.[citation needed]
