Definitely not true by the empirical voting preferences, however, that's not a good argument to move away from it. If we're to believe Arrow, these other systems guarantee that fate we all don't want. At least the FPTP system has a chance. There will never be a candidate which embodies every local sphere's preferences. In the Presidential system, the successful candidate is challenged to find and espouse the most common values across their nation to complement the majority of preferences. Thus, they'll commoditize that common ideology, rejecting more niche and sophisticated ideologies which otherwise alienates those individual local spheres with disparate and idiosyncratic preferences; that is to say, ideology is commoditized in a similar manner to a big brand soda as it projects from a niche market to a more massive consumer demographic
