There's this wonderful line, written by Arron Sorkin, from the second episode in the fourth season of The West Wing entitled, "20 Hours in America: Part 2," where Toby Ziegler (played by Richard Schiff) outlines the qualifications for the country's next president:
If our job teaches us anything it's that we don't know what the next president's gonna face.
If we choose someone with vision, someone with guts someone with gravitas who's connected to other people's lives and cares about making them better if we choose someone to inspire us then we'll be able to face what comes our way and achieve things we can't imagine yet.
