The nation`s leader makes a stop in the Four-States today. President Bush visited the small Missouri town of Aurora today as part of a two day, three-state tour to push for expanded trade as a cure for the recession. The purpose of his tour is to follow the path of a product from manufacturing to the time it leaves the country. The president`s first stop this morning was a John Deere plant in East Moline, Illinois. He`ll end his tour tomorrow, at the port of New Orleans.
