Only as the legislative branch of government, and electing the other branches, of course. I'd also want it divided into areas like states or provinces within the entire nation so that if 51% of people vote one way and 49% of people vote the opposite way, you don't have half the people in the country disgruntled. Just a few national laws, with every other law being decided in states and even cities.
Democracy means simply that the majority will get their way. Republic protects the minorities and the weak against the majority.
Democracy is two wolves and a lamb voting on what to have for dinner,
