Americans' confidence in the U.S. economy increased sharply after the election, moving from a slightly negative evaluation (minus 10) to a slightly positive one (plus 3). Throughout the year leading up to the election, Gallup's U.S. Economic Confidence Index had been consistently negative.
Of course, that's too quick for anything to have really changed in the economy. The increase in economic confidence mostly stems from Republicans' more positive views after Republican Donald Trump won the election.
In the week before the election, just 16 percent of Republicans said the economy was getting better, while 81 percent said it was getting worse. Since the election, 49 percent say it is getting better and 44 percent worse.
