In 2006, George W. Bush sponsored legislation that would promote and encourage marriage as that optimal arrangement. The Healthy Marriage Initiative was authorized under Temporary Aid for Needy Families (TANF/welfare funds).
Although the social science research is very clear (I recommend reading The Case for Marriage, 2001), I was worried that in a time of economic downturn and administration change that the funding to provide marriage education services would not be continued.
Today I learned that Barack Obama has been a firm supporter of marriage education efforts and plans to continue supporting the funding of such programs. On the Healthy Marriage Initiative homepage, there is a quote from his book The Audacity of Hope, 2006:
"...Finally, preliminary research shows that marriage educaton workshops can make a reall difference in helping married couples stay together and in encouraging unmarried couples who are living together form a more lasting bond. Expanding access to such services to low income couples, perhaps in concert with job training and placement, medical coverage, and other services already available should be something everybody can agree on..."
By placing that quote on the webpage, I am heartened that the research will continue to speak for itself and that programs and efforts to stablize American families will continue.
