New research shows economy healthier under Democratic presidents

From Bob Deitrick and Lew Godlfarb's new book, "Bulls, Bears and the Ballot Box":

• Personal disposable income has grown nearly 6 times more under Democratic presidents
• Gross Domestic Product (GDP) has grown 7 times more under Democratic presidents
• Corporate profits have grown over 16% more per year under Democratic presidents (they actually declined under Republicans by an average of 4.53%/year)
• Average annual compound return on the stock market has been 18 times greater under Democratic presidents (If you invested $100k for 40 years of Republican administrations you had $126k at the end, if you invested $100k for 40 years of Democrat administrations you had $3.9M at the end)
• Republican presidents added 2.5 times more to the national debt than Democratic presidents
• The two times the economy steered into the ditch (Great Depression and Great Recession) were during Republican, laissez faire administrations
