I think this is the conservatives’ latest and most virulent effort at “extreme vetting,” in which the candidate either survives the right’s gauntlet with a disclosure that turns out to be a non-event (and thus potentially harmful to Democrats for hinting it would be otherwise), or — and this may be the preferred outcome — he’s further damaged and wiped out quickly, before the convention. Doing this now, before the convention, would allow the conservatives to replace Romney safely and victoriously with whatever “first team” conservatives the GOP claimed they had that did not run in the primaries.
