I think they've done a good job of writing two very viable candidates. Vinick is a Republican I could vote for, which would be a first for me. Nonetheless, I think I'd have to go with the young, idealist Latino.
If you are an Aaron Sorkin fan, and I am, I understand always lamenting his departure. But I also think it is a tribute to Aaron that he created a situation and these great characters that are so solid that with good writers taking them over they still are viable and compelling.
