That article does not state that "Republicans" tanked the economy. It says the economy is on average worse when a Republican is president. All the cited sources, basically concludes that the performance of the economy is almost entirely based on factors beyond the control of the President or Congress. Which makes sense. The economy is complicated, and people will change based votes on their feelings. The Economy is also notorious for lagging indicators. Political parties often blame their circumstances on the "last" administration. I'm dealing with technical debt and decisions that were entrenched 30 to 40 years ago in many cases. Extrapolating the realities of my experience in different business and technical environments informs me that it's really not this simple. These articles don't really help people understand economics, they are designed to sell you a certain belief.
