Senate conservatives are signaling that a key way to win their support for a Senate healthcare bill is to repeal more of Obamacare’s insurance mandates, but they aren’t saying if a requirement that shields sick people from high premiums must be on the table.

Conservative holdouts have complained in recent days that the draft healthcare bill announced last week keeps too many of Obamacare’s insurer mandates. However, some of the key holdouts have not said whether the Senate should let states opt out of a mandate called community rating that forbids insurers from charging sick people more money.
