The Democratic midterm election sweep could result in changes in economic policies related to trade, spending priorities and artificial intelligence. But the biggest forces shaping the economy aren't going to change just because the party in power did. Affordability pressures , heavy levels of government spending and growth that is dependent on the artificial-intelligence tailwind are likely to persist, economists say. And all of those factors pose risks to the economy. "It's in a very kind of fragile place, and I don't know that it would take a lot to push the economy off the rails, and recession becomes a much greater risk," said Mark Zandi, chief economist at Moody's Analytics.
