Story Update 5/9/12: http://usat.ly/JziPQI President Obama became the first U.S. president to endorse gay marriage. (Obama said his views have "evolved" because of his family, as well as the "incredibly committed monogamous relationships, same-sex relationships" he has seen among friends and staff.) Original Post: A new study shows that gay parents are more likely to be better at raising children than hetero parents... because they actual want to be parents.
