I beg to differ

"The essence of America is openness. History, geography, immigration and fate have established that. The shrinking of the American mind under Dimwit-in-Cheat therefore amounts, for Americans, to a dangerous denial of themselves. Prolonged for another four years, in a second Idiot-in-Cheat term, it would negate the American idea, without which, at least for this immigrant, the United States, as conceived, with all its flaws, ceases to be."

Not from the viewpoint of non-USians. Here's a more accurate assessment:

"The essence of America is insular arrogance. History, geography, anti-immigration-sentiment and hubris have established that. The shrinking of the American mind began long before Dimwit-in-Cheat and amounts, in the oh-so average American, to a dangerous denial of science and rationality. Prolonged for another four years, in a second Idiot-in-Cheat term, kleptocracy would negate what little remains of America's stated ideals, the glaring absence of which, at least for non-Normegian immigrants, the United States, as touted, with its unacknowledged hubristic flaws, continues to be vastly overrated."
