Most people you give osama facts to don't care or are too lazy to do the research.
Dale, your wife sounds intelligent and level headed and reasonable. Since the abortion issue seems like an inroad for you, show her osama's voting record and current platform on abortion at any point of pregnancy, no funding for the baby on botched abortions where the baby will live, federal funding for abortion to anyone at any age, no parental consent for girls of any age, and federal money pumped into "sex ed" without abstinence as an option.
It's enough to literally make a person sick. Present these things to her as you both look across the dinner table at your daughter and it will hit home.
