I previously mentioned that I heard a whole bunch of political speeches last Saturday. One of them [complete video] was by Senator Rand Paul. Near the end of his speech [clip], he advocated a sunny approach to political messaging:

(Yeah, sorry, I'm a Philistine.)
But Keb' Mo' has an alternative explanation, which I think I prefer:
