Todd, I know that you are intelligent enough to reason beyond the chest beating and spin that you so often display here. So I have a few things for you to ponder.
1. In the period from 1945 through 2013, that's 69 years. The Democrats had control of all three branches of federal government for 22 of those years. While the Republicans had control of all three branches for 4 years.
2. In that same time span the Democrats had control of the majority of the branches for 47 years and the Republicans had control of the majority of the branches for 22 years.
So if you look at the chart that I have linked to here,
http://uspolitics.about.com/od/usgovernment/l/bl_party_division_2.htm You will see that much of your case for one party or the other causing either a good economy or a poor economy falls flat.
This will add even more perspective,

It seems to me to place either the blame on, or to give credit to one party or another based on simple chronology is simplistic at best. It would be more logical, to me to judge the party's on their merits, i.e. policies implemented, and the values espoused.
I also think that having a certain degree of change of the party that control of our governance is beneficial to our economy, and I am not the only one who thinks so.
http://www.nber.org/papers/w15400.pdf?new_window=1 I wouldn't expect you to read the entire piece but they lay out the premise on page 2 and start the conclusion on page 35.
You will see that they find a positive effect from occasional changes in the party in power to keep the economy operating efficiently. So perhaps you should be be thankful for the Republican party not just for its help in keeping the economy up and running, but for supplying you with a target.
