The N&O's Under the Dome has audio of Perdue's remarks here.
Of course the spin coming from the governer's mouthpieces is also telling. As reported by wral:
Perdue's press secretary Chris Mackey said the remark had been taken out of context. “Come on," she wrote in an emailed statement. "Gov. Perdue was obviously using hyperbole to highlight what we can all agree is a serious problem: Washington politicians who focus on their own election instead of what’s best for the people they serve,” Mackey said.
Everybody catch that? According to Perdue's office, focusing on one's re-election chances are at odds with doing what's best for the people they serve. But if you are doing the best for the people you serve, won't they reward you with re-election?
And by the way, listening to the audio makes it fairly clear she wasn't telling a "joke" – as indicated by the wral headline.
