...Gingrich has been married three times...
Thanks, olivant...I got it now. I had forgotten about that first marriage.
1st wife Jackie Battley
2nd wife Marianne Ginther
3rd (and present) wife Callista Bisek
And so what he can't be taken seriously for is not that he's been married 3 times & left each wife for the next...but that he's converted to Catholocism and asked God's forgiveness.
I'm sure it'll be worth a try...
