No, even the US has more parties than only those two. In Spain we also had a two party system a lot of years ago, but this changed when the people begone to vote also for other parties than those two, with this we have now several different parties, that makes that there have to create aliances to obtain the mayority do be able to govern, so corresponding more on the reallity of the needs of the people, out of this black and white scheme (or better bright and dark grey). In the US is needed that also enter left wing parties, which represent the basic rights of the people, which currently don’t exist, because they are “anti-american communists”, this is the mantra with which they create the fear in the people to vote it.
