Why all the words?
IT’S SIMPLE: President dont just execute laws, they sign them into law - or not.
1. GOP CONGRESS + GOP PRESIDENT WILL REPEAL OBAMACARE.
2. OBAMA WILL VETO REPEAL.
So OBVIOUSLY the fate of Obamacare depends on who is in the White House. Obamacare WILL be repealed if republicans are in charge.
Sorry for shouting but you are seriously lost in the weeds and missing the point.
Actually the Supreme Court is likely to shut it down before Congress acts.
But the fact remains that presidents are duty bound to enforce laws they don’t like.
Obama seems to be quite selective in the laws he chooses to enforce. That is a violation of his oath of office.
