Cool interactive graphic looking at the business cycle looking at 7 different economic metrics and White House, Senate and House of Reps by party. Its a lot more sophisticated approach than merely looking at Market performance by party.
The key question is how much any president can impact this cycle: "Today, Americans save less and earn a lower minimum wage — in real, or inflation-adjusted, terms — than at nearly any other time since 1950. Can voters reasonably expect these and other indicators to change significantly after a new president takes office in January?"
