Actually, undue weight can also results in zero weight.  As it is the whole issue is insinuation and extrapolation of given events.  Just because the article doesn't outright say that Edwards is the father because there was no father listed, it is quite clear that this is the intent.  Now, editors familiar with me consider me to be a FNC fanboy and appolgist regarding conservatives and republicans, so my objection to this is clearly not a partisan point of view.  That said this is in violation of several WP policies.
