Organization: Kaiser Family Foundation
Conducted: January 2019
Exact wording: A national health plan, sometimes called Medicare-for-all, where all Americans would get their insurance from a single government plan
Sample size: 1,190
Overall Findings: 56% support
Party lines: 81% Democrats support, 23% Republicans support, 53% Independents support
Summary: The Kaiser Family Foundation found that 56% of Americans surveyed support Medicare for All. KFF has been running this poll for over 10 years. Additionally, Kaiser asked about support for Medicare for All in other, less straightforward ways, and these changes in wording changed people's opinions accordingly. When asked about support for Medicare for All if it would guarantee health insurance as a right for Americans, 71% favored this. However, when asked about support for Medicare for All if it would threaten the current Medicare program, only 32% favored this. Further, when asked about support for Medicare for All if it would lead to delays in people getting some medical tests and treatments, only 26% favored this. Clearly, the bias of wording drastically alters polling results.
