For ex., do you think Jan Brewer of AZ would nominate Sarah Palin or John McCain to such a ConCon? I know it would be McCain. Here in OH, Kasich is a good guy---but he'd nominate the Tafts or the DeWines, not rock-ribbed conservatives. You might get a decent block of delegates from Scott Walker or Nikki Haley.
The feeling in the Weimar Republic was that they were "morally bankrupt" and/or completely nonfunctional, and surely the Nazis could do better, so what the heck.
