They've got so much in the can on her, the big GOP campaign argument during the general will be which are the top 60 swiftboat ads to run against her.
Whitewater, Travelgate, cattle futures, etc. there's a whole generation to educate or reeducate on Hillary Clinton - educate so they'll hate her and won't trust her like the previous generations. We know the mainstream media will not turn down hundreds of millions from the Koch brothers. The Koch brothers will spend like drunks to hang on to political power. There's an unprecedented amount of GOP ugliness on Hillary coming to a TV screen or newspaper near you in the fall.
The trouble with it is, different from the swiftboating of John Kerry or Obama is a Kenyan Muslim, there's a significant layer of truth to what they'll be telling Americans about Hillary - which will make it very difficult to refute or prevent from sticking or penetrating deeper into the electorate.
Corporate America do not want Citizens United overturned because that could erode their grip on political power. I think the GOP have wanted Hillary as a candidate all along and we're about to see why that is. The corporate media who delivered her primary isn't going to be there for her in the general election - they too want a Republican Supreme Court Judge. They'll take her ad money but their thumb will be on the scale for the GOP. Hillary is going to taste what she dished out to Bernie.
