Biggest health insurer leaves Obamacare markets

The Washington Examiner reports:

The biggest insurer in the nation has exited the Obamacare exchanges in Arkansas and Georgia, as insurers struggle financially in the exchanges.

UnitedHealth will leave the two states and not sell plans in Arkansas and Georgia. The move comes as UnitedHealth has detailed more than $400 million in losses in the Obamacare exchanges and threatened to leave the exchanges altogether.

Other major insurers such as Cigna have said they are losing money but have remained committed to the exchanges. The reason is that they hope the markets will stabilize and the exchanges eventually will become profitable.

Will President Cruz or President Trump be "rewriting" the ObamaCare law from the executive branch because of the lack of competition on the exchanges?
