Heres my initial thoughts:
1. Could that have been anymore folksy?
2. Generationaly this will fall flat among Millenial and Gen X voters, Several important groups though: low information voters, white boomer women, seniors I think this may really resonate.
3. We really won't know how successful this was until Friday or Saturday at the earliest in terms of the trackers. I'm not sure when the Neilson ratings will be out, but judging by the demos they'll release we'll be able to get a good picture of who exactly saw this thing.
