If the state you are in allows it. But don't think under your convoluted theory that a state that outlaws bigamy must recognize a second wife in another state, anymore than they have to recognize your marriage to a male homo from another state .
You are just making up stuff. Show me one case that a state didn’t uphold another state’s marriage. Show me one case where this was validated as a defense toward bigamy. Stop spewing ignorance to inflate Gingrich’s ego.
