Define "most" and "us".

If us means humans living in democracies, I would say that parliamentary democracy has more supporters and constitutional republics.

And even if us == the US, I would argue that most US citizens actually have only a very hazy idea about how their own system of government works, much less how others work. Most of these people think that chanting "USA, USA" in unison is democracy.

That's a very dim view of your fellow Americans. I don't have such a dim view myself; there are certainly people who don't care and didn't pay attention in their high school civics classes, but I've found that most people do care and do pay attention. I wonder if your opinion is colored by recent events, and whether you'd have thought the same in 2008?
