Vital Center
The term The Vital Center was first coined by Harvard historian Arthur M. Schlesinger, Jr., in his 1949 book of that title. He himself objects to the domestic use of the phrase, though:
"Vital center" refers to the contest between democracy and totalitarianism, not to contests within democracy between liberalism and conservatism, not at all to the so-called "middle of the road" preferred by cautious politicians of our own time. The middle of the road is definitely not the vital center: it is the dead center. Within democracy the argument adheres to FDR's injunction to move always "a little to the left of center."
U.S. President Bill Clinton started to use the phrase "vital center" in speeches given during his term of office. Schlesinger wrote an article for Slate magazine noting that Clinton hoped to appropriate this term to mean "middle of the road" or something that his "DLC fans" might prefer its meaning to be, which would locate it "somewhere closer to Ronald Reagan than to Franklin D. Roosevelt". In the Slate article, Schlesinger strongly rejected this interpretation of the term, and reiterated his argument from the 1998 introduction:
In my view, as I have said elsewhere, that middle of the road is definitely not the vital center. It is the dead center.
