Results from our recent study of South Dakota voters age 50 and older found that they overwhelmingly consider Medicaid an important safety net for low-income residents in the state and express consistent support for expanding access to those who earn less than $18,000 per year. Large majorities of South Dakota voters across party lines also consider it important for South Dakota state lawmakers to bring an estimated $1.3 billion in South Dakota tax dollars back from Washington, DC over the next five years to expand Medicaid health care in their state. Two-thirds of South Dakota voters say they are extremely or very likely to vote to expand Medicaid health care to their fellow residents who earn under $18,000 a year.

The South Dakota Medicaid Expansion survey was conducted by phone September 13–28, 2021 with a total sample of 1,000 South Dakota registered voters ages 50-plus.  All data are weighted by age and gender to accurately reflect the population of registered voters in South Dakota ages 50-plus from the sample source.
