That cliff is still there, or a similar one. It's scary to think that something could startle American voters, and we'll jump four or eight years from now. President Trump needs to move us far away from the ledge instead of (like the two Bush presidents) standing still and reassuring us that the abyss is, for the moment, not getting closer.
There is MUCH work to do to try to start righting some of what Obama has dismantled and destroyed. But the left never sleeps. They are gearing up for 2018/2020, and they will continue to undermine, distort, and lie about the right all along the way.
