The fact of the matter is that nobody paid that top rate back then, and it is absurd to suggest that markets were "more regulated" in the 1960s than they are today.

In fact you are conflating tax rates with tax payments: Spending = Taxes (current + deferred)

Clinton cut TAXATION and in so doing actually reduced the size and scope of government, which is much more important than the number of pages in the Federal Register. Bush, on the other hand, increased overall taxation levels (spending) and regulation (hello, do the words Sarbanes Oxley and Patriot Act mean anything to you?). That is why the economy was way better when Clinton left office than when Bush did (either one, for that matter) - not some disingenuous contortion of their Administration's policy agendas.
You are a smart guy, and obviously zealous about promoting your ideology. You shouldn't need to relay on a misrepresentation of Presidential records to make its case.
