In anticipation of upcoming Democratic presidential debates, this poll finds that Democrats and Democratic-leaning independents say that health care is a top issue they want to hear candidates talk about. When asked to say in their own words what health care issue they specifically want to hear about, affordability emerges as one of the top issues. The poll also probes the public about different possible implications of implementing a Medicare-for-all plan and finds that most Americans don’t realize how dramatically such a proposal would revamp the current health care system.
