Again, none of these terms are mutually exclusive. The United States is a democracy, full stop. It is also a republic, full stop. In fact, it is a democratic republic (as well as several other things). There’s no such thing as a “full democracy” or a “true democracy” (though there are direct democracies and representative democracies, both of which are fully and truly democracies).
@SergeantQueen “I don’t think the parties mean you support democracies over republics if you are a democrat and vice versa. I think they are just names.”
Exactly correct. If you go back far enough, the Democratic Party was originally called the Democratic-Republican Party. And when the Republican Party was formed, it was the liberal party in the country. “Democrat” and “Republican” (with capital letters) are just team names, like the Yankees and the Red Sox. That’s what is so ridiculous about partisanship: it’s allegiance to a banner and a brand instead of a set of principles and policies.
