I agree. The "other" 'conservative' would probably (really) be a Libertarian.
The "other" conservatives are "politically conservative" as in "She makes conservative estimates" or "He's conservative with his money."
Not all 'politically conservative' folks believe that the govt should be in the business of 'social engineering' laws like defining what marriage is, or criminalizing victimless behavior.
The 1994 Contract with America was a 'politically conservative' movement. It swept the Rs into Congress on the basis of promises about cleaning up govt corruption, controlling the size of govt, and the like. Now it seems this movement is under assault by the Rs.
So I just thought it would be useful for me to have a ballpark idea of how the percentages breaks down here.
I'd say the older conservatism was more of a realistic libertarianism - mostly against government power and regulation and supporting of freedom, within limits.
Today it seems conservatism just means socially conservative. You can get away with all sorts of government expansion of power and spending and control, but as long as you're pro-life, it's okay.
