Chicago is a real city, the home of the Bundys and the Rhoades/D'Arcys, and called the Windy City, for its powerful winds, and long-winded politicians. It is also seen as politically corrupt. After a series of wars with the local Native Americans, Chicago was founded in 1833, near a portage between the Great Lakes and the Mississippi River Watershed. The city became a major transportation and telecommunications hub in North America today. The city retains its status as a major hub, both for industry and infrastructure, with its O'Hare International Airport as the second busiest airport in the world. In modern times, the city has taken on an additional dimension as a center for business and finance and is listed as one of the world's top ten Global Finance Structures. Chicago is a stronghold of the Democratic Party and has been home to influential politicians, including the current President of the United States, Barrack Obama. The World Cities Study Group at Loughbrough University rated Chicago as an "Alpha World City."
