(Bloomberg) -- Republican Senator Bill Cassidy is making an offer to Democrats he hopes they won’t refuse: If their states like Obamacare, they can keep it.

A doctor who worked for decades in charity hospitals and clinics before joining Congress, Cassidy plans to introduce soon an updated version of his health-care plan aimed at giving states flexibility to keep Obamacare, aka the Affordable Care Act, nix it entirely or transition to a new system of health savings accounts and automatic health plan enrollment.

"You can go to the reddest state and say we have the option to root and branch it, and you can go to the bluest state and say we have the option to keep what we like," the Louisiana Republican said. Under his plan, "Republicans say, ‘You have the option to keep your plan,’ and we mean it," he added.
