Common sense is all relative, many believe it should be common sense to balance the budget. Many social policies are common sense to each side of the debate. In this day and age I do not believe there is any common sense but only partisan rhetoric.
Why is a balanced budget common sense? I am most interested to hear an argument from a Ron Paul supporter, or anyone else really, enumerating specific benefits of a balanced federal budget via spending cuts. Or even better, why immediate large spending cuts reaching for an arbitrary goal (like a balanced budget) would be more beneficial than large short term debt with a sustainable long term debt trajectory. That latter of which, coincidentally of course, is Obama's position.
