Since the difference of perception was about 5%, it shouldn't be much of a problem getting more people to realize that the economy would do better under a Democratic administration. After all, reality is a pretty good ally.
And the poll is months old, so things may have drastically changed. I'm just saying, based on what we currently know, the GOP has (and has had for awhile) a slight edge on the economy.
What's far more relevant is how the economy does before the election. A slowdown probably won't mean anything, but if we get into a recession, Trump will benefit from it. Probably not enough to offset his negatives, but a recession would be a political headache for Clinton.
