U.S. Sen. David Perdue’s latest ad opens with a direct-to-camera assertion from the Republican: “Health insurance should always cover pre-existing conditions for anyone. Period.”

It’s his latest attempt to play to the middle of the electorate in a tight race against Democrat Jon Ossoff. Libertarian Shane Hazel is also in the contest.

The 30-second ad shifts to Perdue’s younger sister Debbie, a cancer survivor who said her sibling is “making a difference for all of us – anyone who says otherwise doesn’t know my big brother’s heart.

Perdue in 2019 sponsored legislation aimed at ensuring coverage of people with pre-existing conditions, but experts claim it doesn’t match the Affordable Care Act’s protections. Ossoff and other Democrats have assailed Perdue for his support of a GOP lawsuit that threatens to gut the Obama-era healthcare legislation.

Ossoff’s spokesman Jake Best called the ad an “election season deceit.”

“Senator Perdue voted at least three times to gut protections for Americans with pre-existing conditions, and last month he said he supports Trump’s Supreme Court lawsuit to overturn the ACA, which would completely destroy protections for pre-existing conditions,” he said.
