Phew.
Honestly for all the craziness that Trump has brought, this has been a fairly stable race polling wise. 2012 was actually a tad more volatile.
That's not true. This race is far more votatile than 2012.
Not in terms of polling. It has been remarkable stable.
Going back and forth between a virtual tie and Clinton+10 three times over is not "remarkably stable".
There are no polls showing a "virtual tie"
There were back in May, in early August, and in late September.
Trump's best number was just above 45%, which is close to Clinton's worst.
