That's damn strange:
"According to the poll, 71% of the voters say that the economy is "good" or "excellent," the highest proportion of favorable feelings on the economy in nearly 18 years of Quinnipiac's polling.
Last month's economic data showed that unemployment in the United States had fallen to 3.6%, a 50-year low.
That said, 45% of voters disapproved of Trump's handling of the economy, while 48% approved. "
In short: The USA economy as far as it affects the average American is in its best shape in modern history and... about half the people, saying that the economy is excellent, disapprove of what the president does on the economy (That is the best in modern USA history).
Not how he does in foreign affairs or how he handles immigration or his cabinet.
Nope, they disapprove of the POTUS' handling of the economy, during an economic miracle...
