Quickie: one reason why Obama supports gay marriage

I support gay rights but question whether the fight for full marriage quality isn’t a wedge issue that will distract voters from more important issues such as war, military spending, the economy,  economic justice, corruption, climate change, health care, taxation, and green energy. Politicians love wedge issues.  Actually, I’m not sure of this. Maybe gay marriage is a fundamental issue of human rights, akin to women’s right to vote and the Civil Rights movement of the 60s.
