Gov. Brian Sandoval on Saturday reiterated his opposition to an Obamacare repeal plan backed by Sen. Dean Heller, but said he continues to support his fellow Republican’s bid for re-election.

Sandoval, speaking at the National Governors Association meeting in Washington, also indicated he might support an increase in the federal gas tax, noting that Nevada localities have approved fuel tax indexing.

The governor said he remains fully behind Heller’s re-election bid despite his fellow Republican’s embrace of a plan that Sandoval opposes to replace Obamacare, formally known as the Affordable Care Act (ACA).

“We’re not going to agree on everything, that’s the nature of politics,” Sandoval told reporters in between panels during the first day of the National Governors Association (NGA) winter meeting in Washington. “I fully support him in his United States Senate race,” said Sandoval, who is chair of the NGA.

At issue is a bill Heller co-authored with fellow Republicans Lindsey Graham of South Carolina and Bill Cassidy of Louisiana that would repeal and replace the ACA.

Sandoval on Saturday underscored his opposition to the bill, known as Graham-Cassidy, because it would cause Nevada to lose between $600 million and $2 billion in federal funding by 2026 if enacted, according neutral calculations from various health-care organizations.

“I’ve already been on record of not being in support of Graham-Cassidy,” Sandoval said. “I don’t want to do anything that would diminish the health-care benefits that our state has received as a result of the Affordable Care Act.”

The measure includes language to provide block grants to states to fund the kind of health-care system they choose, instead of directly funding Medicaid or providing subsidies to make health care more affordable to lower-income people. The bill would also cap funds per beneficiary and end the expansion of Medicaid.

Under the ACA, more people were made eligible for Medicaid and federal funds were provided to allow states to expand coverage. Nevada was one of 33 states, including the District of Columbia, that expanded Medicaid.

The battle over health care hasn’t died down since the Republican-led Congress failed to repeal and replace the ACA last summer. Trump included Graham-Cassidy in his fiscal 2019 budget blueprint, a move that Heller applauded in an effort to link arms with the president on the issue ahead of a possibly difficult primary. His opponent, Danny Tarkanian, has sought to drive a wedge between Trump and Heller.

While Sandoval opposes Graham-Cassidy, he noted that “it doesn’t mean that [the ACA] can’t be changed, or improvements can’t be made, and I am ready, willing and able to work with anybody to do that.”

Sandoval is known as a moderate, and, when asked, would not say if he voted for Trump in the 2016 election. “I’ve already responded to that question,” he said.

During the election, in May 2016, he said he would vote for Trump after Florida Sen. Marco Rubio, who he initially backed for the GOP nomination, then Ohio Governor John Kasich dropped. In June, Sandoval wavered after Trump called into question the ability of U.S. District Court Judge Gonzalo Curiel to be fair because of his Mexican heritage and Trump’s calls to build a wall along the southern border. At the time, Curiel was the presiding judge in two lawsuits against Trump.

Meanwhile, on Monday, Sandoval and the governors will meet with members of Congress, including House and Senate Republican and Democratic leaders.

Among the topics that are expected to be discussed is infrastructure.

“I think one of the conversations is going to be about infrastructure and how that’s going to work,” Sandoval said. “I’m sure other things will come up because a lot of spontaneous issue will come up.”

He didn’t rule out supporting an increase in the federal gas tax, but warned that electric vehicles would not be counted under a gas tax.

“That’s a conversation that has to be had,” Sandoval said.

He noted that voters in Washoe and Clark Counties, the state’s two most populous counties, have approved ballot initiatives to index the state’s gas tax to inflation in order to keep up with the rising cost of labor and materials.

“As a result of the fuel indexing, there’s been a monumental investment in infrastructure and road construction, particularly in Las Vegas,” Sandoval said, adding “it’s working really well.”
