An Axios analysis released Wednesday found that spending on healthcare advertisements has exceeded $65 million in 2019 as dark money organizations, the insurance industry, and Big Pharma ramp up their campaigns against Medicare for All and other proposed reforms.

“More than half of all issue advertising this year has been on healthcare,” according to Axios, “and that spending will only increase as the 2020 campaign gets closer.”

Doctor Patient Unity, a dark money group that purports to represent doctors but doesn’t publicly disclose its members, has been the biggest spender on healthcare ads this year, Axios found. The group has spent $26 million to date in 2019 into an effort to defeat bipartisan legislation aimed at curbing surprise medical bills.

The organization sent mailers to the Michigan district of Republican Rep. Tim Walberg earlier this month warning that billing reform efforts in Congress are “the first step towards Socialists’ Medicare for All dream.”

Axios also reported that One Nation, a GOP dark money group aligned with Senate Majority Leader Mitch McConnell (R-Ky.), was among the top five groups that spent the most on healthcare in 2019. In June, the Republican organization launched a nationwide $4 million television, radio, and digital ad campaign against Medicare for All.
