A Reuters/Ipsos poll shows 85% of Democrats and 52% of Republicans support Medicare for all.

Why it matters: This single-payer system has divided the Democratic Party internally and gave Republicans a new way to attack Democrats in 2018. But this poll is the first to suggest that a majority of Americans on both sides of the aisle actually like this policy and that it could be a winning issue for candidates.

By the numbers: Two-thirds of Democratic nominees in 41 battleground House districts "want to expand the government’s role in healthcare," per Reuters.

• At least 70 House Democrats have joined the "Medicare for All" caucus, with more expected after the November midterms.
• And most House Dems support a Medicare for All bill, which has "six members of the Blue Dog caucus of fiscally conservative Democrats signing on as co-sponsors," Reuters notes.

Be smart: This policy is only going to get more attention as we head into the 2020 presidential election, when it will likely be a litmus test for Democratic candidates.
