You're a couple of centuries too early.
In the future, they might be able to take some Reagan DNA, some Giuliani, some Bush, (anyone want some Buchanan too) etc, mix then up in a test tube, and clone a candidate to run a couple of years later.
But in this day and age it is easy to disparage a successful performer like Giuliani in comparison to the perfect phantom.
This isn't an odd coincidence, either. Most Americans recognize that for all intents and purposes, New York City isn't even really part of the United States anymore.
