Why there won't be a civil war

There are lots of seats still up for grabs, but I took a screenshot of this from the NYT to show how red and blue is pretty mixed up within most states:

At the time of writing - nothing is 100% clear, except that it was not a "red wave".   Seems most likely that the Senate may be the same as it was (Dem control with the VP vote), but lose the Reps by a small number.  (Although some are saying it is still conceivable that the Dems keep the Reps by one.  That would be impressive...)
