Even if Clinton wins, and the Senate flips to the Democrats, it will only delay the inevitable.  The lunatic fringe of "Christians" (I use the term with a great deal of skepticism), racists, conspiracy theorists, anti-intellectuals and robber baron capitalists is going to eventually propel the Republicans into power.  What happens then will be the stuff of nightmares.  Canadians should be doing their damnedest to elect a government that is going to start preparing to deal with a neighbour that will not just be benignly neglectful of its relationship with us, but will be actively hostile to many of our goals, contemptuous of our sovereignty, and likely to be willing to use force to take whatever we have that they want.
