Instapundit linked to "Schumer's shutdown reveals: Democrats will destroy America just to spite Trump." While hyperbolic, it's not enough of an exaggeration for comfort. While probably not willing to "destroy" America, I think many Democrats would be willing to cause damage to all of America if it inflicted severe pain on Red America.
And I'm virtually certain many republicans would happily damage America if it inflicted sufficient pain on Democrats. Indeed, that's at least part of what the election of Trump was. Perhaps Trump hasn't actually damaged all of America as much as might've been expected, but prior to his election, I definitely got the feeling that a lot of Trump voters supported him believing that it was quite likely he was going to be like Samson and pull the entire temple that is America down, but it was worth it because it would damage Democrats and the elite.
So there are a substantial number of people on both sides who are willing to sustain damage and pain if only it hurts the other side more. That's really not a good situation, especially if it festers for decades. Someday, the Left and the Right of the United States will be just like the Palestinians and the Jews, forever at each others' throats and forever killing each other with no possible solution.
Have a nice day!
