A young veteran, just back from serving in Afghanistan, drives a cab in Manhattan while he writes the next Great American Novel.  After picking up a nervous, sweating fare near Grand Central Station, he drives the man to Washington DC.  

Upon exiting the cab, the man is struck by car but survives and runs away, leaving a briefcase behind that contains unbelievable data that if true, indicates that every American Presidential election since 1948 has been rigged by the release of false statistical information.
 
An alliance of four econometric forecasting companies have been compiling, manipulating and releasing polling data for over 60 years, successfully 'predicting' the outcome of each presidential election.

They will reveal this information to the right people for the right price.

Knowing who will be the next US President years in advance is information foreign countries, multinational companies, and billionaires world-wide would, and do--pay big money for.

When it is determined that proof of that information is in the possession of a wanna-be writer, a price is placed on the cabbie’s head. While the author-in-waiting can take care of himself, it is his wife, also back from Afghanistan, who the bad guys should fear most.
