"in American politics, an elected official whose power is reduced because the person who will replace them has already been elected"

Bush would have been a lame duck if he had lost the election- Kerry would have taken the office on Jan 20. So until Jan 20, Bush would been serving as a lame duck. Now, loosely speaking, a second term of any presidency can be called a lame duck, but usually this is used as a president nears the end of his term. And usually it applies when the congress is of the opposition party. Hence Bush isn't a lame duck. Bush also has a mandate.
Thanks for playing.
