This is in no way meant to prognosticate or in any way reflect what the future may look like. To be taken as intended, suspend your ideas of reality, for a brief moment.
Imagine that you are a Republican, of the most Tea Party variety, of the most Benghazi-shouting type.
Imagine that you have lived through 8 years of Clinton, at least 8 years of Bush, and then another 8 years of Obama.
Now, imagine that Sanders or O'Malley win the Democratic primaries, and at the end of it all, imagine they get Hillary Clinton to be their Vice Presidential running mate.
Naturally, this leads to you living through another Democratic victory, and another 8 years of a Democratic President.
Now imagine, at the end of it all, in 2024, Hillary, though she is 76 by then, decides to run again, and this time she wins the Presidency, and as a result, we get yet another 8 years of a Democratic President.
Imagine if you had to experience this fate in their shoes.
