[EX Q]: (CNN) First, consider this: It's the summer of 2019 and a dozen Democratic presidential candidates are gathered onstage for a debate somewhere in the Midwest.

"Who here tonight supports moving the United States toward a single-payer, or 'Medicare for all,' taxpayer-funded health care system?" Pause it there and rewind to January 2016 in Iowa.
