Systematic Attrition — Robert C. Waggoner

Systematic Attrition is a tale of murder at the highest levels of government. A left wing group is determined to set the world right by changing the USA from a democracy back to a socialist dictatorship. A warning is given to a member of the Brad Pratt team over the computer forecasting the demise of high ranking politician. The team scrambles to find the assassin only to discover the assassin was from China, but contracted from the USA. Once again the Brad Pratt team is called upon to thwart the take over and to right the balance of a democracy. Take risk; it's a good read.
