A GOP Senate could take on Obamacare — but not repeal it

“A Republican-controlled Senate cannot repeal Obamacare, no matter how fervently GOP candidates pledge to do so on the campaign trail this fall. But if they do win the majority, Senate Republicans could inflict deep and lasting damage to the president’s signature law.
Republicans are quick to say they are not yet measuring the proverbial drapes. But they are taking the political measurements of repealing large parts of the health law, considering which pieces could be repealed with Democratic support, and how to leverage the annual appropriations and budget process to eliminate funding or large pieces of the law.
Initial targets are likely to include the medical device tax, the individual and employer mandates, the 30-hour workweek to qualify for coverage, and spending on a preventive health fund that Republicans call a slush fund.”
