That theme is one of relative obscurity. ...
These people can thus have a history created for them. Nobody knows them. A historical construct is presented to the public, and anything now beneficial to their image is left out.
Sure. Somebody picked them. Carter, Clinton, and Obama all made the cover of Time early on, and all went to (I don't want to sound conspiratorial here, but I believe it's on the record) CFR, Trilateral or Bildebergers meetings before running (not so much to take orders as to get a general sense of the direction they were expected to take the country or the world). Because they had been so little known it was easy to create an image for them that may not have been supported by facts.
Fiorina (and Sanders) though, haven't had the full treatment. If one of them does get the nomination, they'll more likely have earned it on their own than some others who've gotten there. Somebody like Ben Carson or Herman Cain also emerged from obscurity, but if either managed to get a nomination it won't be like anybody gave it to them.
We’ll, I tend to agree with you at this point, but I’m not sold on the idea the GOPe isn’t pulling some strings hoping to knock Trump out, then one of them out as well to get to Bush.
For some reason they are enamored with the Bush klan, or sure seem to be.
