"Fiscal conservative" is another increasingly ambiguous term that muddies that characterization.
Some people mean that term to preclude robust entitlement regimes and promote a Randian survivalist society, some mean "socially liberal" to encompass said entitlements, some merely equate "fiscal conservative" to mean that regardless of how money is spent it is done efficiently or with a balanced budget.
For instance, I have an accountant friend who considers himself, and wants a president to be, a social liberal and fiscal conservative. But he's firmly a social democrat when it comes to entitlements spending, and is just meaning to convey that revenue is spent wisely and strictly.
