Interesting politics. It would appear Obama owed some favors and appeared for this reason alone. There is no way really that his appearance at this late date could make any difference in the bids because all the bid reports were in and read and all the delegates’ “lost luggage” that needed replacing in potential host cities had already been replaced (or not, as the case may be).
It was a long odds mission for the President.
My own take on Chicago would be how could anyone get anywhere in a timely fashion?
I drove from Windsor to Chicago in 2.5hrs- and then from the one side of Chicago to the other in another 3 hrs! Good thing I arrived before rush hour!
