A majority of Democratic voters believe the U.S. economic system is unfair, according to a new Hill/HarrisX poll.

Fifty-seven percent of Democratic voters said the country's economy is mostly or somewhat unfair while 43 percent said it is mostly or somewhat fair. By contrast, seven in 10 Republican voters said the U.S. economic system is fair.

Independent voters were split on the issue, with 49 percent said the economic system is fair and 52 percent reported that it is unfair.

For Americans overall, the March 1-2 survey found 53 percent of registered voters said the U.S. economic system is mostly or somewhat fair while 47 percent said the opposite.

"Most Democrats feel that the economy is unfair whereas Republicans tend to feel that things are OK, things are fair, things are not rigged, however you want to look at it. I think that really speaks to the political climate right now and the messaging Democrats are hearing from the presidential candidates.

"On the Democratic side, there is definitely a higher level of both animosity and anxiety about that where they do feel that there is a deeper gulf of income inequality developing and they don't buy into the fact that the economy is doing well," she added.

Sanders, who is behind in the race for delegates following last week's Super Tuesday contests, has upped his attacks on the former vice president, criticizing him for taking money from billionaire donors.

Sanders, a democratic socialist who has made fighting income inequality the centerpiece of his campaign, has not accepted anything but small-dollar donations.

The Hill-HarrisX poll was conducted online among 1,037 registered voters between March 1-2. It has a margin of error of plus or minus 3.1 percentage points.
