Republican House leaders have scheduled a vote for Wednesday to repeal extensive healthcare reforms passed and signed into law last year. As the new majority in that chamber, they are expected to pass such a proposal. But with Democrats still holding the majority in the Senate, as well as the power of the White House veto pen, the odds of reform being overturned are not considered serious. Wednesday still could mark a seminal moment because it could be the start of a promised campaign by reform critics to dismantle provisions piece-by-piece, such as by withholding funding or denying other crucial aspects.
