He is currently a member of the Democratic National Committee and, therefore, a superdelegate to the 2008 Democratic National Convention.

As a member of the State Assembly, Gruszynski authored the Wisconsin Environmental Education Law, Farms for the Future Act, and served as chairman of the Assembly's Colleges and Universities Committee.
In 1994, Gruszynski decided against seeking reelection, and instead ran unsuccessfully for United States House of Representatives from Wisconsin's 8th congressional district losing to the incumbent, Toby Roth. Gruszynski again ran for the House of Representatives in 1996, but failed to receive the nomination of the Democratic Party, losing to Jay W. Johnson, who would go on to win the seat.
