Are democrats more conservative than republicans?

Using the US-specific definitions of Conservative and Liberal (which, differ greatly from most of the rest of the world), as a party, the Democratic Party is less conservative than the Republican Party.

Now, this obviously also depends on the politicians under discussion. In addition, we usually split a politician's views on economics from those on social issues. So, it is entirely possible to have a politician who holds mostly Liberal views on social issues, and mostly Conservative views on financial/economic issues. And, the inverse is also possible (though, less common).
