I have noticed that most of the questions you ask have to do with social work. Therefore, I assume that you are interested in Senators Debbie Stabenow and Barbara Mikulski because they were both social workers before they entered politics. This is the aspect of their “journeys to the Senate” that is most likely to be relevant to you.
Barbara Mikulski is a Democratic Senator from Maryland. She was born in 1936 and is now 78 years old. Mikulski attended Catholic high school and college in Baltimore and then went on to get a Masters in Social Work from the University of Maryland in 1965. She worked as a social worker and as a community organizer. She first became involved in politics when opposing the construction of a highway through the Fells Point area of Baltimore. This involvement led to Mikulski running for and winning a seat on the Baltimore City Council in 1971. She ran for the US Senate in 1974 but lost. She then won a seat in the US House of Representatives in 1976. She served in the House until 1986, when she won election to the US Senate.
Debbie Stabenow is a Democratic Senator from Michigan. She was born in 1950 and is now 54 years old. Stabenow attended Michigan State University and then got her Masters in Social Work (graduating magna cum laude) from Michigan State in 1975. During this time she did some work with youths in the public schools. Stabenow was in politics even before she finished graduate school. She won a seat on the Ingham County Board of Commissioners in 1974. She served on that board until she was elected to the Michigan State House of Representatives in 1979. She served in the House until she was elected to the State Senate in 1990. She served four years in the State Senate. In 1996, she was elected to the US House of Representatives. In 2000, she became the first woman to be elected as a US Senator from Michigan.
