PERSONALLY ATTACKED?

A telling and all too common moment from this week's debate:

EDWARDS:...And the most important issue is she says she will bring change to Washington, while she continues to defend a system that does not work, that is broken, that is rigged and is corrupt; corrupted against the interest of most Americans and corrupted...(APPLAUSE) BLITZER: All right...

Can anybody explain to me what's personal about that attack? Brings me back to a certain incumbent's decision four years ago that every criticism of his record was "political hate speech." And does she disagree with the idea that the system in Washington is broken, or that she's been defending it?
