Sometimes us old Florida crackers call it Cape Kennedy, it used to be called that in the 60's I think, and then was changed back to Cape Canaveral.
My understanding was a mapmaker overstepped his authority in naming the Cape during all the sympathy after the assassination, and when somebody pointed it out, the name was quickly changed back.
Something similar happened in AZ. The Governor (a Dem) was in a hurry to rename "Squaw Peak" (cultural insensitivity, ya know), and she ordered it to be renamed after a soldier killed in Iraq. Turned out the soldier died when she took a wrong turn and drove a Humvee into the teeth of a bunch of enemies. Her friend was captured by some very confused Iraqis, who didn't know what to do with her.
The law prohibits naming places after people until 5 years after they die to prevent this sort of fiasco. Napolitano was a Dem so she just ignored the law. I give you better than even odds the Florida mapmaker who renamed Cape Canaveral was a Dem too.
