There's a constituency in this country that's unserved by either party - those of us who are conservative on taxes and other economic issues, but moderate on social issues.
That is true. The problem is that I'm not sure there is agreement on exactly where you're drawing the line between "economic issues" and "social issues". What it
seems like you're describing is a form of libertarianism. The problem, though, is that "economic conservatives" like Kasich really aren't, because their definition of "social issues" has broadened to included truly
economic issues like health care.
What has happened with Kasich is that he was a budget hawk in Congress. But now that he's become a Governor, he wants to remain a budget hawk on the
state level, but now supports even more federal spending because it's not coming out of his pocket/budget. That's why I've really turned on the guy as my own governor. He is fighting hard to preserve the federal financing of the Medicaid expansion, when there is no early reason why any such expansion shouldn't be paid for on the state level. And it's simply because he wants to claim the mantle of being a fiscal conservative, while actually sucking greedily at the federal teat of infinite decifit spending.
