How soon a bill will be filed in Congress to overturn DOMA is anyone's guess. If it were to pass President Obama has said he would sign it, although he prefers civil unions to marriage.

Even if the bill is filed this session, it may find difficulty getting to a vote. In addition to opposition from Republicans and anumber of conservative Democrats, mainly from Bible belt states, Speaker Nancy Pelosi (D-Calif.) seems in no rush to advance repeal.

At her weekly press conference last week, Pelosi suggested there may not be enough votes yet for repeal.
