This has been one of my questions from the beginning.
I also want to know what impacts the same sex marriage would have for employers. Should employers have to provide health benefits for a groups of people who are the highest risk for AIDS? Wouldn[t that action all but bankrupt small employers with premiums they can't afford?
The spector of Same Sex Marriages casts a large shadow, IMHO.
I suspect if same gender marriages are ever recognized nationally, employers will stop providing health and/or other benefits for spouses. I'm not sure how it would impact tax laws, but there would most definitely be some - perhaps no more married/filing jointly for anyone.
