Although a bill that would repeal the federal Defense of Marriage Act is set to be introduced today in the House with about 90 co-sponsors, it is considered to be more of a vehicle to "build momentum" for marriage equality than a bill with a chance of passage, according to this article. Out U.S. Rep. Barney Frank, D-Mass., is not a co-sponsor of the Respect for Marriage Act because he believes the LGBT-rights bills with the best chances of success in this session are the Employment Non-Discrimination Act and a measure that would grant domestic-partnership benefits to federal workers.
