This solid contribution to an immensely important subject gives Congress rather good marks. As the book is strongest in dealing with trade policy, it is too bad that it could not cover passage of the 1979 Trade Act which broke new ground in executive-legislative relations. There is little emphasis on the influence of the outside world or differences in the character of issues. The rather labored effort to provide a new explanatory theory is not very fruitful, but the old ones are soundly drubbed.
