Fiscal conservative makes complete sense to me. It suggests someone that is otherwise socially moderate. Probably the majority of the country.
Bingo. We had PLENTY of social conservatism with Bush, but not dime's worth of fiscal conservatism. What was the result? We alienated the educated and affluent Republican voters. And, what was the practical implication? We only have 40-seats in the Senate, lost the House and the Presidency.
If the Republican party doesn't get back to its fiscally conservatives roots, it's doomed. They'll be able to carry a few Southern states with the people who vote exclusively on cultural issues. That's it.
People (the fiscal conservatives and social moderates) voted for Obama because he campaigned like a fiscal conservative. Sure, he was lying and people are on to him now, but that how he campaigned. So, he won.
