Correcting chubby-faced potato-boy wasn't enough? Constantly covering the same subjects as asked by Russert repeatedly wasn't strong enough?
In case you didn't notice, this was a grilling under the guise of an interview and I think the president did an EXCELLANT job of defusing a contentious and irritating Russert.
Tell us, have you had a chance to see and review 'the interview' again after your original viewing?
