Elizabeth Edwards says she's not surprised that she and husband John Edwards won a poll on happy marriages among presidential candidates.

She says jokingly that the competition wasn't very tough.

The Ladies Home Journal survey released last week shows 52 percent of women thought the Democratic couple from Chapel Hill are
happily married. U.S. Sen. John McCain and his wife, Cindy, led
Republican candidates with 35 percent.

Elizabeth Edwards made the comments Tuesday night at a Raleigh
bookstore, during which she read from her book, "Saving Graces."
Edwards also answered audience questions about grief and talked
about her recovery from the death of the Edwards' son, Wade.
