No you didn't.  Even going by the most liberal definition, the oldest Z people were born in the late 90's, and would have about as much memory of the Bush administration as I do of Clinton, i.e. very little in the way of anything substantial.  The Obama and TRUMP (or Hillary) Presidencies are likely to have a much bigger influence on the voting habits and attitudes of Generation Z.
