This video is a microcosm of politics in today's American society. Whats starts out as a reasonably civil debate between these two, quickly devolves into a shouting match.
It's typical of what we can expect to see in the coming years. I think that the Rosie Vs Trump Affair, coupled with this kind of exchange sets the tone while lowering the bar, for this kind of discourse. And it will only stand to get worse, if the two parties do not alienate their extremes and return to a more civil relationship with the opposing sides. I doubt it's going to happen, but one can wish.
