I imagine that it won't be too difficult, under current guidelines, for a marriage tribunal to declare null Mr. Gingrich's first marriage. Which will be all that is necessary to free him to marry in the Church.
Mr. Gingrich was 19 and his bride was 26, his former high school geometry teacher. A declaration of nullity arising from psychological defects on the part of one or both parties shouldn't be too tough to achieve, at least with current American tribunals.
In that Mr. Gingrich couldn't validly contract a second marriage while his first marriage was still putatively valid (even if it were to be later judged invalid), his second marriage is automatically a nullity.
Assuming no marital history on the part of his new “bride,” and there you go!

Aha. That marriage, indeed, is likely to be null, and in turn collapse the second one.
That was nothing. His wife is twenty-three years younger than he and I guess they had an extramarital affair while he was still married to his last wife.
