Be optimistic all you want but that is not going to change the math. We (Americans) are being invaded and out bred at a rate that will see our nation unrecognizable in a matter of a few decades. It's like the Texas sized asteroid in Armageddon headed straight at the USA. Being optimistic is fine but it will do nothing to prevent or even delay impact.
Were using a different metric to define victory. If your concern is for the future of aging socialists in NE cities, then the outlook is bleak. If your concern is partisan politics, then things are grim. But if our concern is the future of our families, our coreligionists, our philosophy, our faith, our health, and countless other things that actually matter, then things are doing very well.
And once again Ill point out that Politics is a scam and were suckers for playing. That doesnt mean that the rest of our lives need be pessimistic. See tagline.
