No repeal, no replace
The promise to repeal and replace the Affordable Care Act, the sweeping health insurance law also known as Obamacare, regularly drew roars of approval at Trump campaign rallies. There was a two-year window when Republicans held both the House and the Senate that President Donald Trump might have had enough votes to deliver.
The effort fell short in 2017 when three Senate GOP defectors stalled the Republicans' best hope for repeal.
"There is no chance the Senate will pass anything plausible on Obamacare repeal and replace this year," said University of Pennsylvania law professor Allison K. Hoffman.
