Some people can't wait for death or retirement before they celebrate their next savior/martyr.
In some cases it's extraordinarily quick. When Obama had been in office barely 100 days, the Webster Magnet Elementary School in Moot's backyard of St. Paul, MN changed it's name to the Barack and Michelle Obama Service Learning Elementary School.
There are at least 13 schools now renamed after Obama. There are dozens of streets named after him, including one in Tanzania. There is a mountain in Antigua and Barbuda now called Mount Obama. There is a serious proposal to rename Midway Airport to President Barack Obama Airport. Honolulu International Airport is also a candidate.
There has also been disturbingly serious rumblings to rename Chicago's flagship O'Hare International Airport after Obama, but considering who O'Hare is
named after, I can't imagine that ever happening.
