28 years earning, or 28 years in general? Either way, the only Democrat president was Clinton, who governed from the middle, presided over a historical innovation that created a ton of wealth (much of it false), and was pushed into tax cuts by a GOP Congress. Regardless, unless presidents do something drastic, like cut taxes, which Bush did and it stimulated growth and somewhat shortened, somewhat forestalled a recession, or double the capital gains rate, like Obama plans to do, their effect on the economy is not as much as it is made out to be. Right place, right time, wrong place, wrong time, etc. Depends on where the economy is in cycle. Bush should have taken a knife to the corporate rate, and eliminated the capital gains rate, but he didn't have the political capital to do so.
