Congressman Fisher is a wonderful, likeable character. (At long last, a Republican on TV is a good guy!) His Vietnam backstory is very powerful...and when he confides in Johnny, I was near tears.
I find it amazing, Sarah's reasoning for supporting Stillson. It's clear she doesn't like him at all--she knows he's a slimeball (and her wisecracking at him is just gold!). Still, she thinks Fisher needs to go (for an unspecified reason).
By the way...the fact that there's also a Democrat running speaks volumes about Sarah. She doesn't support that guy--she supports Stilson, who's running to the right of Fisher. Hmm....
