In a matchup against businessman David Perdue, Nunn leads 45 percent to 41 percent while another 7 percent said they did not favor either candidate and six percent said they were undecided.
The poll comes just a few days after the Georgia primary where Nunn cleanly won the nomination but Kingston and Perdue were forced into a runoff that will take place on July 22, as none of the candidates in the field were able to get enough votes to prevent a a runoff from happening. Kingston and Perdue were the top two vote-getters.
The Rasmussen poll of 750 likely voters was conducted May 21-22. It had a margin of error of plus or minus 4 percentage points.
