The Senator's Wife by Sue Miller

I decided to give Sue Miller another try in this year of Senators and Presidential hopefuls. The story centers around Delia, whose unfaithful husband, is Senator Tom Naughton. The fact that he cheats on his wife with his daughter's friend who is their holiday houseguest is just one of the reasons he is an unlikeable character. But Delia seems genuine and so does her friendship with Meri, the young woman who, with her husband, moves into the other side of the Naughton's duplex. The last chapter of the novel made me simultaneously disgusted with all of the characters. Miller's ending is cheaper than a cheater.
