Quote from Mercor:
The numbers reflect the fact that the republican president left a better economy for the Democrat.
In the first year the president has no input, his is stuck with the budget of the last president. So they need to stagger the time frame by one year , start it in his second year.
If that happens the republicans do better
There actually have been studies that look at exactly what you are trying to say. Unfortunately for your reasoning, no matter what way the studies are done, looking at a year lag, or more, the democratic administrations are always on top.
Here's a couple more fun facts for you:
1. Under democratic administrations, all income levels rise. In fact, the lower income groups rise the fastest of all. Under republicans, only the top groups rise.
"Under Democratic presidents, every income class did well but the poorest did best. The bottom 20% had average pretax income growth of 2.63% per year while the top 5% showed pretax income growth of 2.11% per year.
Republicans were polar opposites. Not only was their overall performance worse than Democrats, but it was wildly tilted toward the well off. The bottom 20% saw pretax income growth of only .6% per year while the top 5% enjoyed pretax income growth of 2.09% per year. (What's more, the trendline is pretty clear: if the chart were extended to show the really rich â the top 1% and the top .1% â the Republican growth numbers for them would be higher than the Democratic numbers.)
In other words, Republican presidents produce poor economic performance because they're obsessed with helping the well off. Their focus is on the wealthiest 5%, and the numbers show it. At least 95% of the country does better under Democrats.

2. A fascinating tidbit is that the last year of every republican administration (but probably ending with this one), the last year is much better than the three previous. In every case, the Fed has altered its monetary policy to favor growth. The funny thing is, this only happens in the last year of a republican administration, never a democratic administration. Fed bias, perhaps?
"It shows economic performance during election years and it's a mirror image of the top chart: Republicans produce better overall performance, and they produce especially stupendous performance for the well off. Democrats not only produce poor overall performance, they produce disastrous performance for the well off, who actually have negative income growth.
In other words, voters aren't necessarily ignoring economic issues in favor of cultural issues. Rather, Republicans produce great economic growth for all income classes in election years, and that's all that voters remember. They really are voting their pocketbooks.
Bartels doesn't essay an explanation for this. Do Republican presidents deliberately try to time economic growth spurts â and are Democratic presidents too lame to do the same? Is it just luck? Or is the difference somehow inherent in the different ways that Democrats and Republicans approach the economy (with Democrats typically focusing on employment and Republicans on inflation)? At this point, your guess is as good as anyone's.
Bottom line: if you're well off, vote for Republicans. But if you make less than $150,000 a year, Republicans are your friends only one year in four. Caveat emptor."
