When it comes to President Donald Trump’s plans to replace Obamacare, one about face has followed another.

The president’s Monday announcement that Republicans won’t vote on an Obamacare alternative until after 2020 revealed the White House’s confusion on a top issue that is likely to play a huge role in the 2020 congressional and presidential elections.

Trump’s unexpected proclamation came just days after his Justice Department backed a legal effort to gut the 2009 Affordable Care Act. “The Republican Party will soon be known as the party of health care,” Trump told reporters last week.

But Trump retreated Monday after an aggressive lobbying effort by Senate Republicans, who warned in a series of phone calls that he risked driving his party off an electoral cliff by forcing Republicans to take ownership of the health care issue.
