What still staggers me is that either D'Souza or Gingrich are regarded in any way as "thinkers". They are not. They are self-promoting charlatans, with not an ounce of decency, personal or professional, between them, who see ideas as weapons to be used, or sources for personal advancement and enrichment.That's Andrew Sullivan, nailing it. Why conservatives allow these frauds to fleece them time and time again is beyond me; there's obviously a huge, lucrative market for thinly disguised snake oil on the right, and it doesn't appear that there's anything these folks can do to ruin their reputations as long as they aren't publicly disloyal.
If you want more on D'Souza, Dave Weigel's piece is quite good.
