President Trump has threatened to cancel key ObamaCare payments to insurers as part of an effort to make the health law “implode.” But he is yet to follow through on that threat, leaving insurers in a state of anxious uncertainty.

The next sign-up period for enrolling in ObamaCare begins Nov. 1. The Obama administration ran advertisements to encourage enrollment, but Trump officials have signaled that promotion effort might come to an end.

Indeed, the Trump administration cancelled some ObamaCare ads upon taking office in January, which was the end of the last sign-up period.
