Quote from Cache Landing:
There is a difference in their smugness.
McCain's smug grin is because he really has no idea about what Ron Paul is saying. To him it is something like when the adults speak to Charlie Brown.
MWAAA WAAAA MWA MWAAA.......
Romney's smug grin is because he thinks RP is a kook with only congressional experience. Never having been held responsible to implement those ideas in the real economy. He understands what RP is saying, but knows that in the real world the problem is much more complex than that.
Besides that, I'm getting less and less inclined to lump Mitt in with "The Establishment". Right now his entire problem is that it is him against the establishment.
