The Elon University Poll released Thursday has 36 percent of those surveyed this week approve of McCrory's job performance, compared to 46 percent in April. Those who disapproved grew from 25 percent in April to 46 percent.
The Republican governor has received negative attention from hiring decisions at the health department and signing legislation from the GOP-led legislature. The General Assembly's approval rating is 32 percent.
"This is all a reaction to the failed leadership of the governor and the legislature," said Ben Ray with the North Carolina Democratic Party.
Ray says McCrorys sliding numbers make sense.
"Pat McCrory ran as a moderate and now he's attempting to govern as a tea party conservative and the voters are punishing him for it," said Ray.
Mitch Kokai, with the conservative John Locke Foundation, has another theory. It has to do with the media.
"Part of that is there are actually scandals going on," said Kokai.
Kokai isn't saying coverage of the governor is off base, but rather that a barrage of critical stories is bound to take its toll.
"What you're hearing about Pat McCrory is about what people don't like," said Kokai. "You haven't heard much about what he's done or new initiatives."
The poll also shows three in five people say the state is on the wrong track.
The poll sets Obama's approval rating at 38 percent, compared to 45 percent in April. Congress' approval rating is 14 percent.
The Elon poll of 701 registered voters has a margin of sampling error of 3.7 percentage points.
