Hillary Clinton delivered a MUCH tighter speech than her Unity, NH introduction. Longer, punchier, and, because she is the local Senator here, much more comfortable.
After two weeks campaigning and fundraising together since Unity, Hillary Clinton has not only transitioned very naturally from Obama's competitor to Obama's fellow campaigner. In that new role Clinton seems able to reflect on her own campaign more smoothly; both she had Obama acknowledged the "ugly biases" that sometimes flared up during the primary fight.
Obama just took the stage and, despite the crowd's willingness to give him a long standing ovation, quickly thanked and quieted the audience before diving into his own speech; a typical move to help stick to the day's schedule (his next event is in 3 1/2 hours in Virginia), but a tad unnatural for Obama.
Photos look good, they'll be up later.
