I don't see the establishment being all that upset with Santorum, surely not enough to throw the election to Mitt. If anything it shows the system works as the choice came down to roughly the two least tarnished people in the field and rejected the more "compromised" ones. If you count it as conservative VS moderate the conservative side won by a landslide. Now if the Conservative side can rally behind one person and not split the vote allowing Mitt to win by a technicality we might get somewhere.
