Republicans have made repealing and replacing ObamaCare the centerpiece of their campaign promises since 2010.

Now that Donald Trump has won the election and Republicans control both houses of Congress, the GOP is set to make good on their promise.

But one group of establishment Republicans is fighting tooth-and-nail to throw a monkey wrench into the repeal and replace efforts.

Sixteen Republican governors presided over states that employed the ObamaCare Medicaid expansion.

Now five of those governors are writing Congress demanding they keep the Medicaid expansion in place.

Leading the charge is left-wing “Republican” Ohio Governor John Kasich.

Kasich repeatedly lectured Republicans during the presidential campaign that accepting government-run healthcare was the only way to get into Heaven.

He lost every contest to save his home state and usually finished in a humiliating position at the bottom of the pack.

Politico reported on Kasich and other establishment Republican governors fighting to preserve a core component of ObamaCare:

President-elect Donald Trump heaped more pressure on resolution of the issue this week when he vowed to “repeal and replace ObamaCare essentially simultaneously” after the Senate confirms Rep. Tom Price, his pick for HHS secretary.

But Trump’s push comes as at least five of the 16 Republican governors of states that took federal money to expand Medicaid are advocating to keep it or warning GOP leaders of disastrous consequences if the law is repealed without a replacement that keeps millions of people covered. They include Massachusetts Gov. Charlie Baker, Michigan Gov. Rick Snyder, Ohio Gov. John Kasich, Arkansas Gov. Asa Hutchinson and Nevada Gov. Brian Sandoval.

And more Republican governors may join with a Friday deadline to submit written proposals to Republican leadership on the Hill.

Establishment Republicans who argue keeping the Medicaid expansion in place but support ObamaCare repeal are not telling the truth.

The two go hand-in-hand.

And in a sign that worried many conservatives, these pro-ObamaCare governors are meeting with House Republicans.

Politico also reported:

There are signs they are getting a hearing, at least: In the House, GOP lawmakers are speaking to four or five expansion state governors to see if they can find ways to address their concerns, said Rep. Chris Collins, a New York Republican acting as a liaison between the House and the incoming Trump administration.

“We don’t want to leave them hung out to dry on the expansion,” Collins said.

Senate Finance Committee Republicans, meanwhile, are hosting a meeting with Republican governors next Thursday to discuss Medicaid.

Like the rest of ObamaCare, the costs of the Medicaid expansion are spiraling out-of-control.

CNS News reported the program’s costs rose 49% higher than previously reported in 2015:

“In a recent report to Congress, the Centers for Medicare and Medicaid Services said the cost of expansion was $6,366 per person for 2015, about 49 percent higher than previously estimated.

“We were told all along that the expansion population would be less costly,” said health economist Brian Blase with the Mercatus Center at George Mason University in Virginia. “They are turning out to be far more expensive.” Blase previously served as a GOP congressional aide.”

Republicans would like to ‘block grant’ Medicaid to the states in order to save money.

But establishment Republicans are fighting to defend the entrenched ObamaCare Medicaid expansion.

And this is complicating the GOP’s efforts to repeal and replace ObamaCare.
