Run-off 2016 election

What if the US had a run-off election when neither candidate breaks 50% of the vote? Similar to countries like France. Hillary and Trump would face each other in a nationwide contest, with all other candidates eliminated from the ballot.

I think she would win ~ 52.5% versus 47.5%.

Republicans tend to do better when it's not Election Day.  Trump wins.

Is this a runoff, like a different vote being held a few days or weeks later, or just ranked preferences? Because a runoff could mean Clinton looks at the results and makes changes to her strategy, such as focusing more on the Upper Midwest.

No, I mean a run-off one or two weeks later. Direct popular vote, no electoral college.

Angry Trump voters would show up again, feeling such a system is "rigged" or whatever.  Trump still wins in my mind.
