"I see the distincy possibility of the GOP fracturing in 20 years. America will descend into a three-party Hell on Earth, with no clear majority and a declining sense of nationality from increasing immigration and socialist policies. As America weakens from within like the Empire of Rome, its world stature will also decline. Woe unto Bablyon, that whore!"

What is interesting to speculate on, is the fact that we will still be physically and economically powerful long after our national character is gone, where will that lead to?
