I'm assuming the daughter is not lacking in familial support (Cassidy's statement certainly is supportive of her and the child) and has access to more than just the basic necessities of life. I haven't checked, but I suspect this senate candidate is not poor by any stretch.
Chances are his daughter will be absolutely fine. Same with the child--we're not talking a single-mother living on welfare situation.
The only one I see whose life might be potentially messed up is the candidate, but even that may not be true. This gives him a chance to show off his Christian forgiveness and love for his family and babies and such. In fact, I bet his constituency will eat this stuff up.
So... WIN-WIN-WIN!!! (At least for them. Not those other women he slut-shames, who don't have money and family and benefits and privileges to get them by. But he can't be expected to deal with every mess he causes now can he? Just the ones in his own house.)
