If you go back far enough, it's where the term comes from, but it doesn't make sense today. That would nominally make it an oxymoron for a "conservative" party

If you go back far enough, it's where the term comes from, but it doesn't make sense today. That would nominally make it an oxymoron for a "conservative" party to ever propose any kind of change, but clearly they do. It's a fairly common outcome for political words to get stuck to changing movements rather than identifying unique positions and policies over the course of decades and centuries.
