For Republicans in (and out) of a Congress they totally controlled, it would have been scorched-earth tactics all the way. Not a law, not a Supreme Court justice, not an achievement would they have allowed her. The investigations, which never really ended, would have revved up instantly. Impeachment was already on the table before Election Day.  And yet, in one area she would have been on the job and had a free hand from day one: foreign policy, especially in America's wars and conflicts in the Greater Middle East and Africa. 

For that, a president no longer really needs a Congress for which "war powers" are a thing of the past, a Congress that, in twenty-first-century America, couldn't defund a war if the planet's future depended on it.  Wars, assassination campaigns, military "pivots," and Special Ops raids across significant parts of the planet are now really just the commander-in-chief's business.  From Washington to Detroit, Kansas City to Portland, Hillary Clinton would have been dead in the water, but from Syria to Afghanistan, Yemen to Libya, Iraq to Somalia, the Clinton White House would have been on the job.
