The poll also shows half the voters give a positive job assessment of Sen. Johnny Isakson, R-Ga.
InsiderAdvantage conducted the survey Thursday for Fox 5 Atlanta and Morris News among 502 registered voters. It has a margin of error of 4 percent.
When asked about allowing guns at school, 57 percent are opposed while only 34 percent favor it. Another 10 percent are undecided.
Since the 1990s, guns have been barred on campus, even for those over age 21 who got a judge to issue a permit to have a concealed weapon. Legislation that would have repealed the ban was one of the most controversial measures in this year's General Assembly session, stalling just in the final moments over House and Senate disagreement about wording.
Many conservative Republicans argue that the U.S. Constitution's Second Amendment prohibits any restrictions on gun ownership.
The new survey shows they are in a minority. No age group, race or gender supports ending the campus gun ban.
"If the Republicans really insist on pushing this thing in 2014, it could be a litmus test that burns them badly in general elections and even in the closer-in suburbs of Atlanta in GOP primaries," said InsiderAdvantage CEO Matt Towery.
Three-quarters of blacks surveyed oppose campus guns, and two out of three women do as well. Those in the age group most opposed are the parents of today's students by 62 percent, between ages 45 and 64.
However Republicans might take comfort in results showing Isakson has a 50 percent approval rating. Just 30 percent disapprove of his performance while 20 percent are undecided.
For the middle of a politician's term when no campaign ads are building enthusiasm, that's a healthy approval level, Towery said.
And the survey may offer insights into what type of candidate Peach State Republicans should nominate to replace Sen. Saxby Chambliss next year.
"An Isakson-type candidate is one who is clearly conservative, but not prone to grandstand or be rash in reacting to issue. He or she is more of a statesman, and although conservative, does not scare off female voters, who tend to be more towards the moderate side on some issues," Towery said. "Such a candidate would be strong enough on core conservative issues to be acceptable to GOP voters who vote conservative and to general election voters who are conservative on fiscal issues but a bit more moderate on other matters."
