a useful interactive map created by the New Yorker which demonstrates the possible scenarios of the likely outcomes in the two Gaytterdämmerung cases before the United States Supreme Court expected to be announced by Thursday June 27.
As I have indicated in the graphic, the most likely outcome is that DOMA is struck down in U.S. v. Windsor and Proposition 8 is struck down due to a lack of standing by proponents in Hollingsworth v. Perry. This would result in same-sex couples having access to full state and federal marriage equality in 13 states and the District of Columbia by the end of the summer (Delaware's marriage law goes into effect on July 1; Rhode Island and Minnesota on August 1).
The great thing is by this time next week we will know with great certainty what the marriage map will look like in the near future.
