Trump is still waiting for the Democrats and/or the Republicans to provide a fix/repeal/replace for Pelosicare.

He is willing to sign such an improvement/replacement.

The Democrats and Republicans are looking to the mid-term elections; both parties only care about that short-term political goal; and the ability to blame whatever happens on the other party.

Pelosicare will be in much worse shape by November of next year; neither party really cares.
