I think Vinick was the better candidate
I am nearly through with season 6 and Vinick just won the Republican nomination. I don't know if they unearth some deep dark secret in the 7th season, but as far as I can tell, he is the most bipartisan politician in this entire show. He is what being a republican is supposed to be about (not talking about each of his positions on each of the issues, but his overall demeanor). I prefer him even to President Bartlett. He has tact and candor and he cares deeply about the American people, not just winning, or beating the democrats. He has far more experience than Santos and he infuses realism and wisdom into his idealistic view of politics. I know he doesn't win, but at this point in the election, I think he should.
