Three top Republicans are pushing an alternative to ObamaCare that would scrap the law's mandates while keeping the tax credits that help low-income people buy private insurance coverage. An outline of the plan was made public late Wednesday by Senate Finance Chairman Orrin Hatch (R-Utah), House Energy and Commerce Chairman Fred Upton (R-Mich.) and Sen. Richard Burr (R-N.C.). The plan — released the same week that the House cast its first vote to repeal ObamaCare of 2015 — will compete with several other replacement options as the GOP tries to coalesce around a response to a looming Supreme Court decision that could dismantle the law.
