How important is candidate age?

All three of the presidential candidates now leading the Democratic primary field are 70 years of age or older. Thirteen of the remaining candidates are 60 or under.

These facts have been much written about, but do they matter? …

My purpose here is less to explore the impact of candidates’ ages, and more to examine how we reach conclusions about these matters from polls. Such “analysis” is not nearly as straightforward as it appears. CONT.
