One sided debate

In this political ad, Hubert Humphry attempts to ask the public exactly what has nixon done for you? This seems to be the biggest problem in campaigns especially of late. What legislation has a candidate been a part or in the past?
This ties into Nixon's ad in 72 of "Nixon Now". He shows his Foreign Policy but no other domestic policy. The ad is obvoiusly a one sided piece of propiganda, but provokes the viewer to ask what the republican party had done for the public in 1968.
