Republican political strategist Todd Rehm says the spot’s softer tone reflects criticism that Perdue has been too negative.
“David Perdue learned a lesson from the primary that going unrelenting negative can have some downsides.”
However, Rehm says it’s difficult to make the case that Kingston is liberal.
“To call Jack Kingston not as conservative is one thing,” said Rehm. “But to call him a liberal when he had the highest rating from the American Conservative Union is bending the truth to the point of breaking.”
