It was, looked like White House was trying to force a vote that was either going to squeak by or fail hugely depending on which way GOP moderates broke.
Doubt it the end of them trying to Repeal and Replace but certainly a spanner in the works.
I thinks it's more about Trump's ego. He was about to lose, so to save face, no vote.
Kinda like all the lawsuits he's settled out of court.
