The downturn started before the 2000 election and Clinton's last year in office reflects diminished results. The amount of a president's influence on the economy could be a topic for legitimate discussion. But Republicans have claimed loud and long that implementation of their fiscal policies would result in prosperity for all. So much so that they own the results of their policies. I for one am not going to let them run from accountability in that regard and then take credit for favorable results that fall into their laps by coincidence.
I did not initially cite the following article because it did not include an analysis of Junior's economic results compared to other presidents, and also because I was unsure of the methodology used to determine S&P performance. It is important to use the exact same criteria in such a comparison.
Over the years, several studies have shown that the stock market has fared markedly better under Democrats than Republicans. (see:
"The Presidential Portfolio")
The difference, according to Pedro Santa-Clara and Rossen Valkanov, both professors at the University of California Los Angeles Anderson School of Business,
is much too large to be random and cannot be explained by fluctuations in the business cycle. Nor can it be explained by higher interest rates in Republican administrations. The UCLA professors looked at data going back to 1927. Our own study of the post-World War II presidencies confirms their results. We found that the S&P 500 has averaged a total return of 14.1% per year under Democratic presidents since April 1945, and 11.8% under Republicans. The best total returns--17.4% per year--were under Bill Clinton, whose presidency ranked first in economic results. (see:
"Presidents And Prosperity") Gerald R. Ford ranks second, followed by Harry S. Truman.

Republicans can't promote prosperity (except for rich people) even with their colossal deficit spending. As the numbers show, supply side economics, AKA the trickle down theory, have never been anything more than an attempt to find moral justification in taking from the poor and giving to the rich.
