Paul Tsongas (February 14, 1941 – January 18, 1997) was a United States senator from Massachusetts, and the 1992 Democratic nominee for President.
He first entered politics as a city councilor, and then served two terms in the United States House of Representatives. In 1978, he was elected to the Senate. In 1984, however, he was diagnosed with cancer, and left the Senate. After fighting the illness, he returned to politics and in 1992 ran for his party's nomination for President. He ran a strong campaign, and succeeded in winning the New Hampshire primary, and eventually South Carolina.
He promised a "New Democratic Party", incorporating pro-business legislation along with social program reform. His Vice-Presidential candidate was Al Gore. Unfortunately, he was easily targeted as the "Second Dukakis", a Massachusetts Greek liberal. That along with continuing questions about the remission of his cancer, cost him the election to George H.W. Bush.
These questions actually proved important, as Tsongas' cancer DID reoccur, and he died of it in 1997.
