As several of you have pointed out, I have used the term "democracy" where the term "republic" or "indirect democracy" might be more appropriate. Nevertheless, the question still stands. Since we seem to have agreed that the "Journey to Babel" Vulcans were part of the Vulcan delegation, how does this explain the fantastic preponderance of Terrestrial sailors, captains, and admirals in Starfleet? It would seem that (in Starfleet, at any rate), Earth is vastly overrepresented in comparison to other planets. It is probably safe to assume that the same can be said for the civilian government.
Well, there was the U.S.S. Intrepid in "The Immunity Syndrome," whose crew of 400 consisted entirely of Vulcans.
For all we know, there are Starfleet vessels full of Andorians and Tellarites, too.
