Republican leaders are strongly considering an amendment from Texas Sen. Ted Cruz to let insurers sell plans that don’t comply with Obamacare’s insurance mandates as long as they sell some plans that do.

The idea behind the amendment is to address conservative concerns that the bill doesn’t repeal enough of Obamacare’s insurer mandates that conservatives say are driving up premiums. However, it is not clear how the amendment would spread risk among the people buying the Obamacare plans and the likely cheaper plans that don’t comply with Obamacare.
