Moreover, some are worried that House Republicans may not garner the necessary votes to replace the Affordable Care Act, or Obamacare, further fueling concerns over Trump’s ability to pass his planned tax cuts and deregulation initiatives.

“It’s an illustration that perhaps this isn’t going to be a process whereby things that are proposed get rubber-stamped,” Mark Luschini, chief investment strategist at Janney Montgomery Scott, told the Wall Street Journal. “As a consequence it jeopardizes perhaps the market’s confidence in the ease and passage of corporate tax reform, which is clearly market friendly.”

If Republicans can’t coalesce around the Affordable Care Act, can they do it around tax reform?”
