Two candidates with ailing wives

In all the coverage over the return of John Edwards' wife's breast cancer, there has been little or no mention of the fact that he now becomes the second current presidential candidate - not the first - to have a spouse afflicted with a serious illness. Mitt Romney's wife Ann, of course, suffers from Multiple Sclerosis, and although the illness is currently in remission, it could presumably return at any time. It will be interesting to see how the illness of both these candidates' wives affects their candidacy and campaigns.
