The estranged wife of South Carolina's adulterous governor said her husband's infidelities make it harder for her to raise morally conscious sons.

'My hope is in the long run they'll be better men for it, better husbands and fathers in the long run,' Jenny Sanford said on 'Good Morning America' today. 'These are weighty subjects to have to discuss with your children.'

Once the name of Gov. Mark Sanford's Argentinean mistress made headlines, the couple's four sons immediately hit the Internet and looked her up on Google, Jenny Sanford said.

'You get one good shot to raise your kids and we've had a lot of challenges thrown on our plate this year,' she said, adding that she believes her husband's mistress 'doesn't look too dissimilar than me.'

Sanford, 47, was thrust into the national spotlight last summer when her husband publicly admitted a passionate affair with Maria Belen Chapur.
