A group crafting a new blueprint to overhaul Obamacare wants Congress to act on its recommendation this summer to avoid Republican blame for high premiums.

The group of more than 40 conservative policy analysts aims to release a recommendation in June to revive the Republican healthcare reform process, according to a source familiar with the effort. The recommendation, which is being spearheaded by the Heritage Foundation and former Sen. Rick Santorum, R-Pa., would convert the law’s Medicaid expansion and insurance subsidies into block grants provided to states. These changes would not apply to traditional Medicaid.
