Today, on Sean Hannity, when Jeff Jacoby asks Tamara Holder to defend a, say, President Huckabee declaring civil rights legislation "unconstitutional", she declares, "that's different, civil right legislation makes sense" And there ya have it....
I might be missing something but its not within the scope of the presidents power to declare a law unconstitutional. If this is regarding DOMA, he merely wants DOMA to withstand a higher level of constitutional scrutiny... an issue that the Supreme Court must decide.
