“It’s a very big concern,” said Democratic pollster Celinda Lake. “The economy is the No. 1 issue out there for people and right now Trump has a very aggressive economic message that seems to cross traditional party lines to voters.”

The unemployment rate, which fell under former President Obama, has dropped even further since Trump took office. In April, it hit 3.9 percent, the lowest figure since December 2000.

Lake said Democrats can’t assume that because Trump’s approval ratings are low, it will translate into voter support for Democrats on the economy.

“We tend to just assume that people will view us as better on this issue and they don’t, and you can’t win elections when you’re behind on the economy,” she said. “To produce a real blue wave, you need to have an economic message.”
