Mario Cuomo belonged to what the late Paul Wellstone called "the Democratic wing of the Democratic Party. An unabashed liberal who vetoed death penalty legislation year after year based on his Catholic beliefs, he nevertheless supported a woman's right to follow her own moral compass in deciding whether or not to choose abortion. Financial problems in New York during his three terms prevented him from implementing many of the social programs for the disadvantaged he hoped to achieve, but he remained an inspiration to Americans unwilling to unravel the New Deal.
Cuomo's 1984 keynote address to the Democratic Convention remains, for me, the greatest appeal to traditional Democratic values I ever have heard. If you missed this rhetorical masterpiece, watch it here.
