Former President Donald Trump is gone and so are his promises to throw out Obamacare. Now the Republican Party is left with figuring out what comes after “repeal and replace.” GOP lawmakers rarely mention Obamacare, and a GOP-backed challenge to the law at the Supreme Court doesn’t appear to be a major threat. Republican attacks on Democrats pursuing a “government takeover” of health care through a single-payer system don’t quite sizzle when President Joe Biden has made clear he wants nothing to do with it.
