The Senator's Wife by Sue Miller
Lately I've been watching the new TV series The Good Wife, which is about a public official who is unfaithful to his wife. Watching the show made me remember how much I enjoyed reading The Senator's Wife by Sue Miller. There's a similar theme going on, the betrayed spouse of the politician, and also a little bit more. Two women -- Delia and Meri -- are portrayed at opposite ends of their lives. Delia is the 70ish wife of the philandering senator and Meri is the wife of a charismatic college professor. An excellent read.
