Gay marriage referendums

Four states--Maine, Maryland, Minnesota, and Washington--are voting on legalizing marriage for same sex couples.  In Washington some heavyweights like Amazon, Microsoft, and Starbucks are supporting gay marriage.  The Roman Catholic Church is opposed.  In all four states the vote is expected to be close.

Opponents continue to argue that gay marriage undermines heterosexual marriage.  Interestingly, blue states that permit gay marriage, like New York and Massachusetts, have much lower divorce rates than the anti-gay red states like Alabama and Mississippi.

Same sex couple marriage is not legal in Pennsylvania, of course.  I expect Mississippi and Alabama to legalize it before the Pennsylvania legislature acts.
