Democracy

Explenation
Democracy both can and can not be interpreted as it's separate ideology as it means different things to different countries. A democracy can be a system where the people vote for a leader such as a president or prime minister that represent another different autonomous ideology from the democracy ideology. But it can also mean that you are a nation which uses people's vote for things such as actions performed by the government. It can also mean other things, but that is up to the person using democracy as ideology. If you are strict on having THE ideology democracy, that'd be an almost fully centrist ideology which would base almost everything upon votes and other stuff like that. Although writing democracy as an ideology when making your nation is tempting since, maybe you want your nation to have elections, but with every election there may be change. So writing democracy might not always be the best as it doesn't really describe the ideology of the sitting party, etc. If you are not a total democracy.
