[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. The network moderator concludes her introductions and tees up the opening question. "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. The caucuses are days away, and Hillary Clinton is fending off an unexpected challenge from Sen. Bernie Sanders. The discussion turns to single-payer, and Clinton balks. "People who have health emergencies can't wait for us to have a theoretical debate about some better idea that will never, ever come to pass," she tells voters in Des Moines, explaining her campaign's focus on preserving and expanding Obamacare, while dismissing the progressive insurgent's more ambitious pitch.Sanders campaigned relentlessly against the Republican bills, mostly in the Midwest and Rust Belt.Public opinion polls have begun to show more support among Democrats for single-payer.
