Why is everyone blaming the president? Last I remember the president executes laws, not creating them.
He was in the thick of it with lies from start to finish, pushing it before it was passed against the groundswell of objection across the nation, and spending taxpayer money on his "you'd like it if you were smart enough to understand it" tour.
His administration is the one who took the lies all the way to the Supreme Court.
His administration is the one who threatened insurance providers who tried to tell the truth about it.
His administration is the one which set up a hotline for people call in to report when someone told the truth about the legislation. Which of course he painted as a lie. But which even the complicit media now admits.
And as to executing laws -- he's the one who has been changing laws from the oval office, not executing them in good faith, but bending or breaking them for his political advantage.
