What McCain did was hard. What Murkowski and Collins did was much harder.

From Vox:

In the early-morning hours after Senate Republicans’ last-ditch attempt to repeal Obamacare failed, a common narrative began to emerge: that while three “no” votes from Republicans killed the bill, only Sen. John McCain (R-AZ) saved the day.

CNN called it “John McCain’s maverick moment.” The Washington Post described it as “The night John McCain killed the GOP’s health-care fight.”

To be sure, McCain’s vote against the bill was dramatic and decisive. He flew back to Washington from Arizona less than two weeks after he was diagnosed with brain cancer, after having surgery to remove a blood clot from above his eye. He made a sweeping speech about returning Senate procedure to a time of bipartisan, transparent cooperation. Then he proceeded to briefly horrify ACA proponents by voting yes on a motion to proceed vote, and yes again on the Republican Better Care Reconciliation Act.

So when McCain cast a performative last-minute vote against “skinny repeal,” it immediately overshadowed the two women Republican senators who did far more to halt Republicans’ reckless efforts to repeal Obamacare. Sens. Lisa Murkowski (AK) and Susan Collins (ME) repeatedly stood their ground against the three health bills their colleagues tried to ram through the Senate.

Murkowski and Collins were the only Republicans to vote against a motion to proceed with the health care bill debate. Both women cast votes against the Better Care Reconciliation Act, which could have led to 22 million more uninsured Americans. They both also voted against the Obamacare Reconciliation Act — repeal and delay — which could have led to 32 million more uninsured Americans.
