Powerful health-care groups continued to rail against the bill, including AARP and the American Hospital Association, both of which urged a no vote. But it was unclear whether the opposition would ultimately derail the attempt, as key Republican senators including Lisa Murkowski of Alaska said they had yet to make up their minds…

In a letter to Senate leaders, the group of 10 governors argued against the Graham-Cassidy bill and wrote that they prefer the bipartisan push to stabilize the insurance marketplaces that Sens. Lamar Alexander (R-Tenn.) and Patty Murray (D-Wash.) had been negotiating before talks stalled Tuesday evening.

The governors who signed the letter are particularly notable, since some are from states represented by Republican senators who are weighing whether to back the bill. Among the signers were Alaska Gov. Bill Walker (I), who holds some sway over Murkowski, a potentially decisive vote who opposed a previous Republican effort to repeal and replace the Affordable Care Act.
