I actually got a few minutes to see what was going on and tuned in to hear her invoking the 10th Amendment!(I thought that was code for racism, that's what the dims have told me ;-)
As she said, nowhere is the word 'marriage' found anywhere in the Constitution, but neither is abortion, but that doesn't stop her ilk.
Of course, the Founders never imagined any one would question marriage. Its amusing to see liberals invoke the Founders as the gold standard for NOT protecting traditional marriage. These are the folks who after all, view the people who founded our country as DWM.
