Matt Towery's Southern Political Report says it's possible given his polling firm's latest survey results.
A survey of 571 registered likely voters in North Carolina’s May 6 Democratic primary shows Sen. Hillary Clinton having moved from a double digit deficit in an InsiderAdvantage poll taken in mid-April to a two point lead over Sen. Barack Obama in this telephone survey, conducted April 29. The survey was weighted for age, race, gender, and political affiliation. It has a margin of error of plus or minus 3.8%
The results were:
Hillary Clinton: 44%
Barack Obama: 42%
