Yeah, remember that episode of Bab-5 where the news networks did a slime-job on Sheridan to make him look like a corrupt politician?
That's what has happened with Hillary, and would've happened to Sherridan - and people would've called him a war criminal too by the media portrayal.

Pretty much this. Based on his values, Sheridan would've run most likely as a Democrat...and holy shit would the Republicans tar and feather him for anything!
