That is a particularly bad comparison. Reagan had the best growth rate among Republican presidents since WWII and Carter had the second worst growth rate among Democratic presidents.
You can see the annualized GDP growth rates under all the post-Truman presidents here. Four of the top five growth rates were under Democratic presidents (and that includes Carter). The only Democrat who isn’t in the top five is Obama, who is at the absolute bottom. The only Republican in the top five is Reagan at no. 4.
The data I’ve seen says the opposite, e.g., compare the economies under Carter and Reagan.
