One can only hope.
Teddy Roosevelt wrote: "...then the end of the Roman republic was at hand, and nothing could save it. The laws were the same as they had been, but the people behind the laws had changed, and so the laws counted for nothing."
Although my disdain for the liberal trance is undimmed, it's not only ideology and human folly that make things fall apart. It is also conditions. I have suspected that the US is simply too big to function as a single country. Add to that all the Balkanizing and it seems less likely that this once great Republic will continue in its present form. Just too big.
And, too diverse. As well as antagonistic.
