As the Democratic race shifts into high gear and the fallout from the impeachment trial settles in I have a respectful and heartfelt cautionary admonition about polling data: Caveat emptor.
Let’s begin with Iowa. Not one poll before the Iowa caucuses accurately captured what was happening. Most of the closing polling data showed Bernie Sanders starting to creep towards 30 percent, with Joe Biden closely behind in the low 20s and Pete Buttigieg somewhere between 15 percent and just under 20 percent. CONT.
