What can he do about it anyway? Gay marriage is not a federal issue.
Appoint judges who support "gay marriage," and who are just as lawless as most of the past half-century's jurists.
This is not really a response to you, but more of a semi-related question to you that I'm asking since you're much more of a legal mind than I.
Doesn't the Constitution require that marriages from one state be recognized by all the others? Shouldn't it then be the Supreme Court's responsibility to ensure that gay marriages and civil unions from MA, VT, etc be recognized in all other states?
His answer to the question will be:
No, not in the case of gay marriage.
