As of July 6th, there are now 15 states which ban discrimination on the basis of gender identity, and there are 21 which ban employment discrimination on the basis of sexual orientation or gender identity (all the states which ban gender identity discrimination also ban sexual orientation discrimination). The six states which do not overlap are: New York, Wisconsin, New Hampshire, Massachusetts, Maryland and Delaware. (One should note that 3 of these 6 states have already enacted marriage equality!) Wisconsin is ahead scratcher because they passed sexual orientation non-discrimination way back in 1982, the first state in the country to do so. There was gender identity nondiscrimination legislation pending in New York and Maryland which died when those legislative sessions ended this Spring.
The Employment Non-Discrimination Act (ENDA) would prohibit employment discrimination nationwide on the basis of sexual orientation or gender identity. Significantly, A version of ENDA (without gender identity protection, thus some people called it "SplENDA") passed the U.S. House under Democratic control in 2007 but failed to be brought up for a vote in the 2009-2001 111th Congress. With Republicans in majority control of the U.S. House it is very doubtful that ENDA will pass that body in the 2011-2013 112th Congress.
