Particularly G.H.W. Bush, who received personal assurances from Sununu, who was supposed to know Souter well, that he was a reliable conservative.
Souter was strongly recommended by Senator Warren Rudman , who had helped Bush win the New Hampshire primary.
Rudman knew that Souter was a liberal and is still quite proud of the way he “fooled” George H. Bush.
Bush , like Nixon, were not really focused on who they nominated, just as long as it was politically expedient. Thank goodness we didn’t let GWB put Harriet Myers on the Supreme Court.
Will FR embrace socialism to make way for Rudy Giuliani as a Republican presidential candidate?
There's a difference between somebody who is poorly advised or "fooled", and somebody who deliberately lies. You can to some degree fix the former, by more thorough investigation, better advisers, or corrective education (as in the Miers case), but you can't fix liars.
Judging from Giuliani's track record, he has a pretty fair chance of being in the latter category.
