The Post’s obituary of Stewart Mott recounts his interesting life and mentions Buckley v. Valeo:

Stewart R. Mott, 70, a General Motors heir and self-described “avant-garde philanthropist” who used his family’s fortune to underwrite progressive social causes and liberal political campaigns, died June 12 at Northern Westchester Hospital in Mount Kisco, N.Y.

. . .

In a statement yesterday, consumer advocate Ralph Nader called Mr. Mott “about the most versatile, imaginative philanthropist of his time” and “a pioneer in many fields well before the large foundations.”

. . .

His $400,000 contribution to McGovern won Mr. Mott inclusion on the Nixon White House’s enemies list with the notation, “Nothing but big money for radic-lib candidates.”

. . .

For years, Mr. Mott cut large checks to causes and candidates. This approach was challenged by post-Watergate campaign finance reforms, leading Mr. Mott to ally himself with conservatives angered by the U.S. Supreme Court’s 1976 decision in Buckley v. Valeo that upheld the $1,000 individual contribution limit.
