Kaine must have an earpiece... he’s backed off on being a total jerk... and his ‘mugging and creepy smugness’ have been dialed back some.
I think Mike Madisow has confirmed that the Clinton campaign are experts at transmitting signals; unlike the presidential debate, this one isn’t in their pocket (but sure on their side.)
