The following could be true:
Decision makers in the Olympic Games selection committee were threatened with losing jobs associated with General Motors if games are not held in Chicago according to a former neighborhood coordinator. Obama’s firing of GM’s CEO Wagoner is seen as a power move by the Administration to control all aspects of life on Earth.

Chicago’s infamous politics has also been heard from. The Daley political machine used part of $1 billion of Chicago federal stimulus funds to pave streets around potential Chicago Olympic site in time for Olympic selection committee final visit on April 2, 2009.

From March 30, 2009 WBBM web site – “IOC site selection personnel will arrive in Chicago Thursday for a week-long stay.  The IOC will choose the 2016 host city in October.”

According to Forbes.com in a March 25, 2009 article, Chicago has more potential hurdles or “potential minefields to traverse” than other cities in running including Madrid, Tokyo and Rio de Janeiro. Also, within the past four weeks, two little discussed kerfuffles have reared their heads.

One, the allocation of revenues from the games are the subject of intense negotiations with the International Olympic Committee, and;

Two, the sudden replacement of the United States Olympic Committee chair[?] with inexperienced Stephanie Streeter[sp]. The suddenness and the $500k salary have upset many of the 1500 delegates meeting in Denver this week. See her curriculum vitae here. Streeter’s former company has ties worldwide. Since leaving, her company has been acquired by RR Donnelley who has seen its stock drop from the $30 range to about $5 in the past year.

The host country is allowed to designate a local sport to be included in the games. The choice is between “popping a cap” and bowling. The Forbes article mentions the popularity of Obama as a factor.

I know not the author, though he does make good points.
