Running from a challenge? Unsurprisingly, that's something they can believe in:

CBS had agreed to host a debate next Sunday at the RBC Center and televise the event nationally. Clinton agreed to the date, but Obama, who had earlier committed to an April 19 debate, said repeatedly he wasn't sure whether he could fit an April 27 debate into his campaign schedule.

Leading Tarheel Democrats—including both Democratic gubernatorial candidates—are in the tank for Barack Obama, and they understand that another dismal performance by a faltering Obama could give the Clinton campaign the opening it needs to finish a bruising primary season strong and throw the nomination process even further into turmoil. They don't want to risk his double-digit lead and his overall viability when it isn't absolutely necessary.
