alt Hacker Newswell this book was written in 2003 and current day events in USA clearly contradict this statement : "two-party system is actually one of the most resistant to single-individual or single-party takeover."
With lots of examples of contrary , where multi party system has not devolved in one man shit show.
North Korea, China, Russia, Uganda, etc. are examples of one party taking over; the USA is just a country that has one party (you don't seem to like) with most (but not all) of the political power at the moment.
