Broadcast live. Here they all are, the seven candidates for the 1988 Democratic nomination. This two-hour special is not a formal debate; instead, the candidates are asked questions in turn by Messrs. Buckley and Strauss; each had earlier provided a taped biographical segment; and each has a brief closing statement. As samples, three of the candidates' answers to the one question they had been given in advance. As Mr. Buckley states it, "In the Oval Office, there are portraits of five Presidents. Each President on moving in plays a little historical musical chairs, exiling one or two Presidents and repatriating substitutes. President Reagan has hanging the portraits of Jefferson, Lincoln, Taft, Coolidge, and Eisenhower.... Whom will you remove? Whom will you resurrect?" Mr. Jackson would put up Lyndon Baines Johnson: "As long as we have the public-accommodations bill and we have the voting rights act, we will have a Lyndon Baines Johnson." Senator Gore would hang Woodrow Wilson, FDR, and JFK, plus two Tennesseans: Andrew Jackson and James K. Polk (although he calls him James K. Knox). And Senator Simon would "like to see a steelworker from Pennsylvania and a coal miner. I would like to see a farm family there, a working mother..." And we're off and running on this superb capsule view of the Democratic field.
