Yes, you're right, Edwards did not leave his wife. That doesn't excuse his behavior. The fact that it was during a campaign makes no difference either. He was campaigning for office. AND, the fact the Elizabeth was in remission doesn't make an affair acceptable...
Just for the record I hope you don't think I was actually defending John Edwards.
The 'in remission' statement was his. I like to put it out there every now & then and since his name was brought up....
