Kinda depends on what he's trying to model. If you mean "predict $ vs Euro, price of gas, price of Wachovia stock one year from now" you are right. But if he's modeling hugely aggregated stuff (inflation, GDP, unemployment, national debt) and the impact his policies would have then it's quite possible he'll get just as robust results from a "simplistic" model as he would from some zillion parameter simulation.
