Here's a great summary by AP about all the activity in the states this year over marriage equality. In brief:
MN and NC citizens will vote on amendments to ban marriage between same sex couples, while
ME will try to get the voters to support marriage in a referendum.
MD , WA and NJ have legislative efforts to legalize marriage between same sex couples, while
NH has a legislative effort to repeal marriage equality
In the judicial sphere, we're still waiting for the next chapter of the Prop8 case. At least 8 DOMA cases are winding their way through the courts.
