The Clinton case is honestly, tough to make. Not because he was full of ****, but because it's very difficult to understand things that IMPROVE the economy. It's much easier to understand thing that hurt the economy. I don't want to sound patronising, but it's enormously complex. Here's a good case for what Clinton did that caused the economic growth we experienced while he was in office:

The Bush case is much easier to make. Bush has cut taxes, which is fine if you cut spending, or at least spend responsibly. Bush has done neither. Let me try a quick and dirty metaphor.
Imagine your family is fairly wealthy and a rich uncle gives you a loan of $25,000. You can pay it back to him without intrest whenever you want, and if you never got around to paying him back he probably wouldn't mind. You decide you don't need the $25,000 and give it back to your uncle. Then you go out and get every credit card you can. You spend all of your income and max the credit cards out so that you can barely make the minnimum payments. You reason that having this crippling amount of debt will give you incentive to get a better job and the new car and suit and house you bought will facilitate that.
It might take you a couple of years to get the job, though, but instead of spending less you get even more credit cards. You max them out too. You're still making the payments so your credit's ok, but you continue to borrow more and more and go further and further in debt confident that your new job will take care of it because you'll make more money in a few years.
You spend more and more every year, while your income stays the same and then at one point you decide to provide for your childrens future and you borrow $100,000 from a bank to set up a trust for them. You'll pay for it with the money from your new job.
Here's the best part though. You get to turn your life over to someone else after four or eight years and they can worry about paying the debt you've accumulated.
That's Bush is doing to the national economy.
Again, it's a lot more complex than that, but there's no argument that Bush is spending massively while cutting revenue with no plan to do anything about it. He's confident it will all fix itself.
