In any case, GDP is a highly volatile, often-revised economic series. Therefore, I wouldn't place too much emphasis on the numbers in the short to intermediate term. But then again, I'm not trying to make a political point. The economy is better now than when Obama exited office, and it also certainly improved during Obama's two terms.
