Republicans often get the nod for being better with the economy. For example, a recent Pew Research Poll of registered voters found that 49 percent of voters trusted Republicans to handle the economy better, while 40 percent trusted Democrats. This post seeks to answer a simple question — is this perception true when it comes to the presidency? Do Republican presidents have better economies?

To answer the question, I looked at a variety of measures. These included measures of economic performance, like Gross Domestic Product or the change in the unemployment rate. I also looked at some areas of criticism for Democrats — that their policies lead to debt and inflation. Then, I looked at President Trump’s favorite measure of performance — the stock market. Finally, because this blog is about inequality, I examined how a measure of inequality did under Republican presidents and Democrats.

The results are presented in all their glory below, but let me summarize it for you. If you are going to vote for a Republican presidential candidate based on their economic performance, think again. The perception that Republican presidents get better economic performance is wrong. Across most of the measures I will present, if anything, Republicans do worse. And you don’t have to believe me. Every measure I looked at came from here or here. Go have a look for yourself. Or, just trust me and read on.

Republican Presidents vs. Democrats: GDP & Unemployment

Probably the two most commonly used metrics of economic performance are GDP growth and unemployment. GDP measures the total output of the economy. Unemployment measures the share of workers who want a job, but don’t have one. To analyze how the various presidents did along these metrics, I analyzed performance from January of the first year of a term to January of the last year of the term. The exception is President Trump, whose measurement I stopped in January 2020, before COVID-19 struck. Presidents with two terms get two observations, and I analyzed all presidents from Jimmy Carter and on.

The figure below shows the results for annual GDP growth. The red bars are Republican presidents and the blue bars are Democrats. The figure clearly shows that during Democratic presidencies, GDP grows faster — 3.0 percent per year vs. 2.3 percent for Republican presidents. And if you think, “well, I bet Trump beat Obama,” then you are wrong. Both of Obama’s terms compare favorably to Trump’s before COVID.

The story is similar for the unemployment rate. Republican presidents saw an increase in the unemployment rate of about 0.4 percentage points during their terms. Democrats saw a decrease of about 1.2 percentage points. During Republican presidencies, unemployment has gone up on average, during Democratic Presidencies it has gone down.

OK, so that’s not great for Republicans. Well, Democrats must spend way too much money right? And that must lead to hyper inflation…right? Yeah, about that…

Republican Presidents vs. Democrats: Debt and Inflation

When we talk about national debt, the most important metric is probably the debt-to-GDP ratio. The idea is simple — if our nation produces a lot of output, then debt isn’t such a problem. Today, the ratio is quite high due to COVID-19 spending, sitting at 1.35. This fact means that the government has 1.35 times as much debt as the nation produces in output…not great. But don’t worry, I didn’t count this against President Trump…again, I stopped measuring his performance in January.

The graph below shows the annual rate of growth in the debt-to-GDP ratio. If you were expecting to see Republicans outperform Democrats on this metric, then you will be surprised. The average Republican saw an annual increase in this metric of 4.6 percent. Democrats had a lower number, at 0.4 percent. So, having a Republican president does nothing to slow the accumulation of debt.

On the inflation front, things do look a bit better for Republicans. During their presidencies, inflation increased by about 3.2 percent on average and during Democratic presidencies by 3.7 percent. Hardly hyper inflation, but a win for Republicans. A lot of that difference is driven by Jimmy Carter’s historically bad 9.9 percent…more than twice any other president during this time period. But, fair is fair. It’s 3 to 1 in favor of the Dems.

Let’s turn now to our current President’s favorite measure of economic performance the stock market. Why he loves it so much is beyond me, since only about half of Americans report they actually own any stock. But, to be honest, I don’t completely understand that man’s preferences. Surely, Republicans do better by this metric. And, surely, Donald Trump beats out Barack Obama. Well, they seriously don’t…and don’t call me Shirly.

Republican Presidents vs. Democrats: The Stock Market

To look at the stock market under various presidents, I turned to the Wilshire 5000, the broadest measure of stock market performance available. For some reason it contains 3,473 actively traded stocks, not 5,000. Look, I didn’t name it.

The figure below shows annual growth in the index during the presidential terms in question. And, it shows that Democratic presidents see better performance during their terms than Republican presidents.

It also seems to be a common belief that Trump’s presidency before COVID was one of incredible stock market growth. And, it had actually been pretty good. But, if you are one of those people thinking you’ve never seen your 401(k) grow like this, then you are either 3 years old or wrong. So, Democrats are up 4 to 1 heading to the home stretch — looking at inequality.

Republican Presidents vs. Democrats: Inequality

To measure inequality, I turned to a metric that I’ve used frequently in this blog — growth in median household income. And, I’m going to be pretty real with you — on this front both parties’ presidents look pretty bad. But, if you are keeping score — and I am — Democrats win. Since Jimmy Carter, Democratic presidents have seen growth in median household income of 0.6 percent per year. For Republican presidents, it has been 0.3 percent per year. Both very low and both much lower than growth in GDP. C’mon America, do better!

In this figure, you can actually see the one thing that President Obama and Trump have in common — overseeing some reasonable growth in median household income. Obama’s second term and Trump’s current term (importantly, pre-COVID) both saw increases in line with GDP.


The scoreboard for this little exercise is below, and it shows Democrats beating Republican presidents by a score of 5 to 1.

Note: All numbers in this table are described above. Aside from the change in unemployment, all numbers represent annual growth rates. The change in unemployment is the difference in unemployment from beginning to the end of the term.

So, if your plan is to vote for Donald Trump because Republican presidents are good for the economy, you need to think again. The evidence suggests the opposite. If you usually vote with your wallet, then it might be time to change parties.
