With the Pennsylvania primary finally over, the Democratic presidential contest will move on to North Carolina, where another fiercely fought Democratic primary is already under way in the gubernatorial race.

The two Democrats running to replace term-limited Gov. Michael Easley (D) continued their high-spending ad war this week, with Lt. Gov. Beverly Perdue keeping her promise to run only positive ads despite a harsh attack spot from Treasurer Richard Moore.

Moore's latest ad charges Perdue with weakening efforts to keep guns out of schools and voting to toughen abortion restrictions. "Is Bev Perdue a Democrat we can trust?" it asks. Perdue's campaign was quick to respond with "From Me," a "positive campaign fact check" disputing Moore's charges, touting Perdue's endorsement by state police and teachers, and reiterating her pledge to avoid negative advertising.

Perdue's camp followed "For Me" with a second hearty dose of positive campaigning: a folksy endorsement spot featuring Andy Griffith. "Nothing could be finer than to be in Carolina with Bev Perdue as governor," Griffith says. Besides contrasting sharply with the tone of Moore's ad, the saccharine endorsement spot could help sway voters on the strength of Griffith's popularity in the state, if the success of his past political picks is any indication.

The airwaves aren't entirely dominated by Democrats, however. The state GOP is stirring up a national controversy with "Extreme," set to debut next week, which uses footage of the Rev. Jeremiah Wright to scold both Perdue and Moore for endorsing Barack Obama. And Charlotte Mayor Pat McCrory has released the fourth in a series of ads featuring him against a white backdrop, touting his record of leadership directly to voters.

In "Jobs," McCrory notes the state's struggling economy and implies that as mayor he created "137,100 new jobs" -- a claim that's faced some skepticism from local observers. "It's a stretch," ruled the Raleigh News & Observer.
