Well now, if a Kennedy wants that seat in Illinois, shouldn't it be a Smith?
Weren't the Smith in-laws the ones who ran the Merchandise Mart in Chicago?
I found this on wikipedia, which in this case, I'll trust.
"In 1945, the Merchandise Mart was purchased for $12.5 million by former Ambassador to Great Britain Joseph P. Kennedy, Sr., the father of future U.S. President John F. Kennedy. Later managed by Sargent Shriver, the building was owned for more than 50 years by the Kennedy family through Merchandise Mart Properties, Inc. until 1998, when MMPI was acquired by Vornado Realty Trust for $450 million in cash and a $100-million-plus stake in Vornado. In early 2007, the building was valued at $917 million.
It looks like the Kennedy clan made some big bucks off of the sale.
