No, 80-90% of Americans don't think the economy was better under Trump
Trump claimed that 80, 85, or even 90% of Americans say the economy was better under his watch. But that's not true. While people feel warmly about the economy under Trump, the share isn't nearly that high. According to a YouGov/CBS News poll from March, 65% of Americans thought the economy was good under Trump, while 28% thought it was bad.
