Here's an oddity worth remembering. On Saturday evening, February 1, two days before the Iowa caucus, when the actual VOTING phase of this forever campaign was at last set to begin, CNN went on the air in a program it had scheduled in conjunction with the Des Moines Register, a program that had been promoted as a live unveiling of the final poll results before the actual caucusing. But they provided no results. The network announced that the pollsters had discovered a glitch in their own procedures that rendered them unwilling to stand by the results. After that announcement, the remainder of the hour-long program was anticlimactic filler. What kind glitch led to such an embarrassing stand down for these two institutions? You can find the particulars yourself with a little googling, and I will leave you to it. I will only say, as I do in the headline above, that poll results these days are sensitive things, best handled with gravest of care.... One of the reasons...
