GOP wonders: Should we repeal ObamaCare's taxes?

Yet voiding those levies erases a mammoth war chest Republicans would love to have – and may well need – as they try replacing Obama’s law. It’s a major rift GOP leaders face as they try crafting a health care package that can pass Congress.

“These are sources of revenue you just can’t discount,” said Rep. Patrick Meehan, R-Pa., a member of the Tuesday Group of GOP pragmatists. He said the money could help “create a soft landing and coverage for those who currently rely on Obamacare.”

Republicans know they’ll need tons of cash, whatever they devise. The figure is currently unknown.

“Whatever we do in replacement is going to cost some money, and is there a way to generate money if we ditch all the Obamacare tax revenues or not? That’s where we haven’t achieved consensus,” said No. 2 Senate GOP leader John Cornyn of Texas, who supports erasing the levies.
