Forget the 18th-century founders, or even the last of the 20th-century giants like FDR, LBJ or Reagan, we have become so downsized and sadly diminished in what we can imagine for American leadership, that we treat the trashy, reality-TV likes of Trump and Palin as contenders to be taken seriously. Poor, pathetic us. Look honey, they shrunk our imaginations. Forget the trade deficit. It's our inability to dream of great leaders that will make us a third-rate nation before long.
