Nevada has become the latest state to scrap its crippled Obamacare exchange and join the federal HealthCare.gov for at least a year.

The Silver State, which had seemed to start strong last October before smashing into a wall of technical problems, is the only state with a Republican governor that ran its own health insurance exchange in 2014. Gov. Brian Sandoval had argued that it was important for his state to steer its own exchange, even though he opposed Obamacare.

But the Nevada exchange board decided Tuesday that its effort couldn’t be salvaged in time for the 2015 enrollment season that starts in November. Nevada becomes the fourth state to admit its enrollment system, which cost tens of millions of dollars, is beyond repair and move to replace it with a substantially new one.

The board of the exchange, known as Nevada Health Link, voted unanimously to end its relationship with Xerox, the vendor that had received a $75 million contract to build the online enrollment portal. Instead, it will fold into HealthCare.gov.
