A poll by the left-of-center Public Policy Polling firm of North Carolina  gives U.S. Rep. Jack Kingston of Savannah the edge over businessman David Perdue in next week's closely-watched GOP Senate runoff.

The automated survey, commissioned by Better Georgia, has Kingston with 47 percent among Republican voters and Perdue trailing with 41 percent. The remainder are undecided.

The poll involved a July 9-12 survey of 516 Republicans who said they would "definitely" cast ballots in the July 22 primary runoff. You can find the crosstabs here, but the poll also found that almost half of the respondents describe themselves as "very conservative."

PPP also did a separate poll of 664 Georgia voters that found Kingston trailed Democrat Michelle Nunn in the Senate contest 44 percent to 41 percent, and Perdue behind her by a slightly larger margin: 48 percent to 41 percent.

It also found Gov. Nathan Deal in a statistical deadlock with his challenger, state Sen. Jason Carter, with Deal at 41 percent and Carter at 40 percent. Libertarian Andrew Hunt was at 8 percent. Deal's approval rating was pegged at 40 percent, and his disapproval rating at 42 percent.

The gubernatorial crosstabs are right here, along with several questions involving Deal's stance on healthcare and his sale of a salvage yard.

The margin of error for both polls is about 4 percent.
