David Gregory speculates that the Edwards' affair may be bad news for Obama. I have a very hard time seeing how Edwards' affair reflects on Obama. What I do know is that this is another of those cases where there is a tacit but uniform agreement among pretty much all reporters and close campaign watchers not to publicly state the obvious: that this is a perilous development for John McCain. Just as Bill Clinton's public undressing in the Lewinsky scandal led indirectly to the exposure of several high-profile Republican affairs, Edwards' revelation will inevitably put pressure on the press in general to scrutinize John McCain under something more searching than the JFK rules they've applied to date. I assure you that this dimension of the story occurred to every reporter even tangentially involved in reporting this race soon after the Edwards story hit yesterday afternoon.
