Fifty percent of voters say that they are concerned that the government will go too far in restricting the rights of citizens to own guns, according to a NBC News/Wall Street Journal poll. More than 45 percent said they were more concerned that authorities would not do enough to regulate access to firearms.

A ban on the sale of the semi-automatic firearms referred to as assault weapons remains relatively popular, according to the poll, with 51 percent of voters supporting such a ban while 31 percent oppose it. 

Forty-five percent said an assault weapons ban would be "worth it because it is one more step that could be done to try to reduce the number of casualties and save lives." Forty-nine percent said such a policy is "NOT worth it because it will not stop the attackers from getting the weapons they need."

Sixty-seven percent of Republicans, 63 percent of rural voters and 50 percent of men offered a positive opinion of the NRA, while only 20 percent of Democrats, 32 percent of urban voters and 34 percent of women said the same.

The poll of 1000 registered voters was conducted June 19-23.
