I thought about this the other day but assumed it would get swamped by people getting pissy over learning that they’re not conservative:
IMO, “Conservative” describes principles that create a preference for certain policies. “Republican” describes a group that promotes policies.
Some of the things on this list are conservative principles (individual freedom, limited government) and some are Republican policies (pro-life, secure borders) that have crept into the definition of conservative because the two are so often used interchangeably.
I don’t think the principles and policies actually align well enough to warrant that type of usage. I see a lot more overlap between the “principles” of the two parties and those of their followers than I do between “conservative” principles and those of either party. E.g. Republicans don’t want a smaller cheaper government. They want to borrow the same amount and pay it toward their preferred government services instead of those of democrats. They don’t want individual freedom, they want to use government to enforce their preferred social norms.
I’d be interested to see a two-stage debate where the parties first agreed on principles-based definitions of liberal and conservative and then went through the platforms of the two major parties to see if they actually had any loyalty to those principle. I don’t think either would fare well.
