(CNN) - It's been a negative campaign and only gotten more negative as the campaign drags on.
But do voters blame either candidate for being more negative than the other? The answer is yes.
Voters in both states were asked if they thought either candidate has attacked his or her opponent unfairly.
In Indiana, 63 percent of Democratic voters said Clinton attacked Obama unfairly. That compares 43 percent who said Obama attacked unfairly.
In North Carolina, two-thirds of Democrats say Clinton attacked unfairly while 40 percent of Obama did.
